Tottenham became the second high-profile scalp in as many FA Cup rounds for Middlesbrough as Chris Wilder's men won 1-0 after extra time to secure passage to the quarter-finals.

Boro academy graduate Josh Coburn was the hero, firing home superbly in the second half of the additional 30 minutes after coming on as a substitute. 

Antonio Conte's men were hoping to avoid the fate suffered by Manchester United last month, but Spurs ultimately paid the price for their wastefulness as the hosts claimed a memorable victory.

Flashpoints were few and far between in the first 45 minutes, but the contest did generally improve after the interval, with Harry Kane scoring only to see his tap-in disallowed for a foul.

Both sides were indebted to their goalkeepers as the game went to extra time, and Middlesbrough were rewarded for their greater endeavour as teenager Coburn landed the decisive blow.

A low-quality first half provided very little to get excited about until 40th minute when goalkeeper Joe Lumley was beaten to the ball out wide as he flew out of his area, but Matt Doherty miscued his eventual effort as he shot over the empty net.

It was hardly the precursor to a second-half onslaught, however, with Boro the next to go close in the 53rd minute through a free Matt Crooks header that went over.

Spurs finally tested Lumley just before the hour, the goalkeeper preventing Eric Dier's 30-yard free-kick from finding the top-right corner, and Kane had a goal disallowed from the resulting corner after tugging a defender's shirt.

Chances began to flow for both sides towards the end of regulation time, with Paddy McNair's last-ditch challenge denying Steven Bergwijn, while Lumley and Hugo Lloris made crucial saves from Isaiah Jones and Son Heung-min, respectively.

Extra time beckoned and not only did Boro look sharp at the back, they carved Spurs open with 107 minutes played, Coburn smashing beyond the helpless Lloris.

Phil Foden was inspired by Lionel Messi in his assist for Jack Grealish at Peterborough United, according to the Manchester City goalscorer.

Foden assisted both goals in City's 2-0 FA Cup win on Tuesday as they reached the quarter-finals of the competition for the fifth time in six seasons under Pep Guardiola.

A pass under pressure to Riyad Mahrez led to the breakthrough on the hour mark, but Foden's ball for Grealish really caught the eye.

His pinpoint delivery was controlled expertly by Grealish, who finished calmly before revealing time spent watching clips of Paris Saint-Germain superstar Messi had helped the pair.

"[The pass was] unbelievable," Grealish told ITV.

"It's funny – before the game, on the coach on the way here, I sit next to Phil, and I was scrolling through Twitter and a video of Messi came up, and it was Messi's passing. Me and Phil were just watching it.

"As soon as he passed that ball, obviously I scored and he came running over to me and said, 'It was just like what we were watching before the game'. Just like Messi, wasn't it?

"Obviously I have that kind of link-up with Phil. It's been a long time coming, because I don't think he's assisted me yet, but it was a good moment for myself."

The goal was Grealish's first in the FA Cup and only his fourth in a City shirt, although Guardiola had spoken before the match of disregarding "the statistics" when it came to his £100million man.

That theme has clearly been consistent in conversations between player and coach, although Grealish finished with a game-high five chances created.

"I expect more," he said. "I want to get a lot more, but I've been speaking with the manager a lot recently and he's been helping me.

"I want to get goals and assists, but he has said to me it's not all about goals and assists. I've played in a lot of big games this season that the manager's trusted me in that I haven't scored or assisted in, but I feel like I've done alright.

"For me personally, obviously I do want to get more goals and assists, but hopefully that will come now for the big part of the season."

Manchester City made hard work of a 2-0 win at Peterborough United to advance to the FA Cup quarter-finals on Tuesday.

Premier League leaders City named a strong side – captained by Oleksandr Zinchenko in a show of solidarity with Ukraine – but toiled against the Championship strugglers.

The Posh had the game's clearest opportunities up until the hour mark when Phil Foden took control of proceedings, teeing up both Riyad Mahrez and Jack Grealish to take the tie away from the home team.

It was reward for City's perseverance, having piled on the pressure from the outset on a patchy Peterborough pitch.

The best chance of the first half came at the other end when Jeando Fuchs got in behind Nathan Ake and saw a low, deflected effort touched around the post by Ederson.

And Sammie Szmodics really should have fired Peterborough in front early in the second period but scuffed horribly wide when the ball fell his way from a long throw.

City were far more clinical when they finally crafted an opening, as Mahrez spotted a gap between the legs of defender Hayden Coulson and squeezed his shot into the bottom-left corner.

Mahrez might have added a swift second when Josh Knight blocked bravely, yet it was only a temporary reprieve for the Posh, who had no answer for Foden.

The England midfielder's sharp pass under pressure found Mahrez for the opener, but he had time and space to lift his head and seek out Grealish for the second – sublime control followed by a cool finish.

Still Peterborough did not give in, and Ederson had to save well from Jack Marriott, although City were comfortable at 2-0 and could have had more – Foden and Grealish each denied before Aymeric Laporte missed an open goal – as they advanced to the last eight for the fifth time under Pep Guardiola.

Oleksandr Zinchenko was to captain Manchester City at Peterborough United on Tuesday in his first appearance since Russia invaded Ukraine.

Ukraine international Zinchenko was on the bench at Everton on Saturday and pictured in tears as both teams showed their support for his nation at Goodison Park.

And further gestures were set to follow before the FA Cup fifth-round tie against Peterborough.

Zinchenko was to be at the forefront of those after he was named as City's skipper on the teamsheet, despite the club initially suggesting regular captain Fernandinho would lead the side.

Fernandinho, who spent eight years in Ukraine with Shakhtar Donetsk before joining City, offered the armband to Zinchenko in a sign of solidarity.

"Our captain decided to give the armband to him to show how important the situation is," Pep Guardiola told ITV Sport. 

"We are all the club behind this gesture, behind our captain, who represents his country."

Zinchenko and Fernandinho were among six changes to the City side, with Jack Grealish also brought in after a spell out through injury.

Guardiola had confirmed on Monday that Zinchenko would be involved, saying: "I think it would be good for him to play and show the reason why he is here – he is a magnificent player – to play football."

Thomas Tuchel called for calm and insisted it is business as usual on the pitch following Russian owner Roman Abramovich's decision to pass stewardship to Chelsea's trustees.

Abramovich announced on Saturday, a day before the Blues' EFL Cup final penalty shoot-out loss to Liverpool, that he is taking a step back from his involvement with the club.

That announcement came three days after Russia began its military invasion of Ukraine to widespread international condemnation.

But ahead of Wednesday's FA Cup fifth-round tie with Luton Town, Tuchel is not letting talk surrounding Abramovich – and wider events in Ukraine – distract his players.

"We try to be calm here," he said at Tuesday's pre-match news conference. "We are calm in the centre of a storm or some noise around us we cannot control. 

"We are not responsible for it. In the end it's best to stay calm and focus on what we love and what we do. This is sports. 

"We have a right to focus on sports, the players have a right to be focused. This is what we can tell the fans, I think this is what the fans saw on Sunday. 

"There is a big situation out there. A lot of commitment from the players of both clubs, from the fans. I think everybody is aware there are more important things. 

"The situation in Ukraine is by far much more important than football. Still, there was a full stadium. Still, we arrived two teams, strong teams, who played a fantastic match. 

"This is what we can do for the fans, to distract them and entertain them. To do what we do with maximum effort and commitment. 

"I don't see any other solution what we can do different."

Probed further on events that are escalating in Ukraine, and whether Abramovich should remain the owner of Chelsea, Tuchel grew irritated with the line of questioning.

"You have to stop. I am not a politician. Honestly, I can only repeat it," he said. "I even feel bad to repeat it, to talk about it. I have never experienced war. 

"I am feeling very privileged, I sit here in peace. I do the best I can. You have to stop asking me these questions. I have no answers to you.

"You always start the question with the same sentence: 'There's much more important things than football, can you comment?'. You decide also to ask me about war. 

"How often do I need to say it? It's horrible. There cannot be any other opinion about it. That's it. Why should we be more distracted than you at work? 

"That's what I mean when I said it in the first place. It's out there. There's more important things out there. This will never change. It's about sports. 

"There's a lot more important things out there. Still, there is a huge distraction going on. We are worried. 

"In the end we try and create an atmosphere to come to work, which is our passion. We are very, very grateful and privileged to have it and it's not that big of a problem. 

"Everybody in Europe has some noise in his head that nobody likes. Maybe the same for you but still you try to do your job as good as possible, the same for us."

Chelsea's six-match winning run in all competitions was ended with Sunday's defeat to Liverpool at Wembley, albeit in a game that finished goalless at the end of 120 minutes.

The Blues now have a second game in the space of four days as they head into an FA Cup tie at second-tier Luton.

After suffering a rare defeat in a major final, Tuchel is hopeful his side can quickly respond this week.

"It should not be too hard to lift the team after Sunday," he said. "Everybody knows we played a strong match to our identity, with full commitment and a lot of quality. 

"You can never control the result. A winner had to be found and it was found after 22 penalties. That tells the story. That should not be the problem. 

"It's only two days. We gave a day off to clear our minds. It was not only a disappointment but physically training, demanding. 

"That leaves us with a one day turnaround to be ready for tomorrow. It's another competition; that's life at Chelsea. 

"We want to be competitive, we want to be in different competitions, so we have to be ready. Is that always easy? Maybe not. 

"This is what we do, what we demand. From me, myself and everybody around the team, last but not least from the players. This is where we are."

Tuchel confirmed that Chelsea have a "massive list" of absentees ahead of facing the Hatters, with Hakim Ziyech among those out of contention for Wednesday's contest.

Jurgen Klopp expects Thiago Alcantara to be in contention to face Inter after the Liverpool midfielder was forced to miss the EFL Cup final due to a hamstring injury.

The Spain international was in tears after dropping out of the starting line-up against Chelsea at Wembley.

Liverpool went on to win 11-10 on penalties after a goalless 120 minutes, Chelsea goalkeeper Kepa Arrizabalaga, who was brought on for the shoot-out, missing the decisive spot-kick.

Thiago will miss Wednesday's FA Cup clash with Norwich City at Anfield and will likely sit out the Premier League game with West Ham on Saturday, but Klopp hopes he will be available for the second leg of the Champions League last-16 tie with Inter, in which Liverpool hold a 2-0 lead after the first leg.

"He's not crying any more," the Reds manager told reporters on Tuesday. "This was a very emotional moment.

"We were all surprised. I watched the whole warm-up, didn't see anything, and I came in the dressing room and he's on the bed, telling me he feels something in his hamstring, which is not good obviously.

"We had to make the decision that he could not start at this moment, when you are that close to playing a final.

"For the one player who won probably the most silverware in the whole squad, or as much as the whole squad together, to show this emotion... I didn't like that he didn't feel that good, but the desire to play the final I liked a lot.

"He's fine again but not fit again. For the weekend, I'm not sure; maybe Milan. After that, definitely."

Thiago has made 20 appearances for Liverpool in all competitions this season.

Jurgen Klopp is not thinking about a historic quadruple this season as he says Liverpool are "close to nothing" after winning the EFL Cup.

Liverpool beat Chelsea 11-10 on penalties at Wembley on Sunday after a gripping goalless draw –  the standard of which Klopp described as "insane".

The Reds' attention quickly turns to the FA Cup and a fifth-round tie against Norwich City on Wednesday.

And Klopp will not look further ahead than that match, despite his side now being candidates for an unprecedented English quadruple.

With one trophy secured and the other domestic cup entering its final stages, Liverpool are also six points behind Manchester City in the Premier League with a game in hand and a trip to the Etihad Stadium to come, as well as leading Inter 2-0 after the first leg of their Champions League last-16 encounter.

"The quadruple? It's a wonderful story," Klopp told a pre-match news conference. "No team yet in the history of English football ever won the quadruple, right? That's because it's really difficult.

"We won the Carabao Cup, we are behind City in the Premier League, we play Norwich tomorrow night after playing 120 minutes on Sunday, and we play West Ham.

"The fun part of [the media's] job is you count the points before we play the games, but we still have to play them.

"It's not that we are even close to think about any crazy stuff like that. We just want to try to make sure the boys are fit enough to face Norwich in a proper way."

Pressed further on others backing Liverpool for a potential quadruple, Klopp said: "That people see us as having a chance, you could see it as a compliment, but I don't need these kinds of compliments.

"It doesn't feel like that. We don't think, 'oh, we are close to winning the quadruple'. We are close to nothing at the moment.

"We are still involved in now three competitions, that's all we are – like some other teams as well.

"It's better that people think we can do good things than people think we are useless, but it's not very important or even helpful, because we face a lot of really good football teams between now and the end of May."

Manchester United won a treble in 1998-99 but exited the EFL Cup to eventual winners Tottenham in the quarter-finals.

City finished the 2018-19 season with three trophies, too, but similarly saw a quadruple bid ended by Spurs, this time in the last eight of the Champions League – which Liverpool won.

"I'm not sure how you get to that story," Klopp said. "Okay, the only team that could win the quadruple is us, because we won the first competition – that's easy.

"But even City, with all the quality they have, in the last few years couldn't win the quadruple. That says pretty much everything."

Antonio Conte insists his outburst following Tottenham's recent loss to Burnley was "strategic" rather than emotional as he reiterated his commitment to the Premier League side.

The 52-year-old appeared to question his own future after last week's 1-0 defeat at Turf Moor when stating he was "not good enough" to fix Spurs' problems.

Conte, who signed an 18-month contract with Tottenham in November, later took aim at his squad on the back of a fourth defeat in five league matches.

That led to reports that the Italian could be heading for an early exit from Spurs, but he backtracked on those comments ahead of Saturday's 4-0 win at Leeds United.

Conte has now further explained his remarks, admitting there is a specific intention behind what he says in news conferences.

"I think that you have to understand when there is a strategy or not and not only an emotional moment," he said.

"It is not right to stay here and explain why I talk in a way and after three days I spoke in another way. 

"Maybe I can explain to you, every time we have a press conference there is a strategy behind it, not an emotional moment.

"I understood that was the right moment, after four defeats in five games and winning the game against Manchester City three days ago, to send the right message, a clear message to myself, the club and also the players.

"We have to know we are here to enjoy football, at the same time to improve ourselves, to ask to ourselves for 100 per cent commitment and desire and also to underline that a team like Tottenham does not exist to lose four games in five.

"If someone understood that my words were from an emotional moment, no. In that moment I sent a specific message to the whole environment and it has happened in the past, when I want to push the situation and the environment in the same direction, because I am seeing we can do better, it is not because it is an emotional moment, it is because there is a strategy behind it.

"Maybe I can explain to you, every time we have a press conference there is a strategy behind it, not an emotional moment."

Tottenham moved back up to seventh with their morale-boosting victory at Elland Road, five points off fourth-placed Manchester United with two games in hand.

Spurs switch focus to the FA Cup on Tuesday with a fifth-round tie away at second-tier side Middlesbrough, who eliminated United on penalties in the previous round.

The north London side have not reached the quarter-finals of the competition since 2017-18 and have not won any silverware since lifting the EFL Cup in 2008.

Conte has made clear that he intends to win at least one trophy during his time with Spurs, but he accepts he has a big task on his hands with Chelsea, Manchester City and Liverpool still involved.

"For sure it's a big challenge for me, for my players because maybe you start this tournament as underdog," said Conte, who has lost only one of his 11 domestic cup matches against sides from a lower division (W8 D2).

"But at the same time you know when you arrive to play this game and you know that there are only four games to reach the final and you start to feel the possibility to see the target, to see the goal close to you and then for this reason we have to try to push ourselves to go ahead in this competition and to try to create problems for the team that usually at this moment they are favourites to win this trophy."

Including replays, Tottenham have never lost to Middlesbrough in the FA Cup (W4 D2), though those two draws have come as the away side in February 1905 and January 2020.

Jack Grealish needs to stop concerning himself with statistics and public opinion and focus purely on his contribution to Manchester City, says Pep Guardiola.

City forked out a reported £100million fee to land attacking midfielder Grealish from Aston Villa in August.

Grealish has managed three goals and three assists from 25 games across all competitions, numbers the England international himself recently suggested do not back up his own personal feeling that Guardiola has improved him as a footballer.

But the City boss says Grealish should take a step back from being too enamoured by the statistics alone.

"Maybe he's wrong. Maybe he listens too much to what people say. It's wrong but the statistics are better and he plays quite similar to Aston Villa in terms of ball contact," Guardiola said.

"He had the chances against Crystal Palace in 20 minutes to score three goals. It didn't happen but it's going to happen. 

"We didn't buy him to score 45 goals. He doesn't have that quality he has another one."

Grealish has missed the past three weeks with a shin problem but is in contention to face Peterborough United in the FA Cup fifth round on Tuesday.

Guardiola is of the opinion that Grealish is not alone in focusing too much on the hard numbers.

"Always we talk about the statistics – the players today play for the statistics but this is the biggest mistake they can do," he added.

"We're involved in that. Statistics are just a bit of information that we have but there are players that make the team play good and they are not into statistics. But the players say how many goals I score or how many assists or...

"With these kinds of situation, they forget everything. Statistics never existed before. It's how you play today if you perform to your maximum, to your best, help your team-mates to make the process defensively and offensively better – it's enough. Thanks to that we are going to win.

"Everyone has agents and managers and everything and say what they have to do better and they listen to a lot of things about what they have to do. 

"He's playing good. I would tell him – I wouldn't tell you – if he's not playing good, but that's not the case."

Tottenham head coach Antonio Conte claimed winning trophies in Europe is easier than succeeding in England ahead of an FA Cup clash with Middlesbrough.

Spurs sit seventh in the Premier League after a 4-0 demolition of Leeds United, five points behind fourth-placed Manchester United, who have played a game more.

Conte's side are still in contention for the FA Cup as well, in which they face Chris Wilder's Middlesbrough on Tuesday, while the north London club were knocked out in the EFL Cup semi-final by Chelsea, who lost the final to Liverpool on Sunday.

Conte insisted it will be a difficult challenge to lift a domestic trophy at the end of the season, given the quality of competition in England.

"To win trophies in England, as I said before, is very difficult," he told reporters at Monday's pre-match news conference. "At the moment it's easier to win in Europe than England. 

"When you start to play the quarter-final, semi-final, final, you have to fight against a top, top team that probably could play the final of the Champions League. It's important to continue to go through in this trophy.

"This happened in the EFL Cup, don't underestimate the semi-final Tottenham reached, because the final was Chelsea versus Liverpool, so to reach the semi-final was a good result for Tottenham. 

"This has to be a boost to push us to improve the level, to be competitive, to try to meet a trophy as soon as possible, because if I speak about the future, you don't understand the time that we need.

"It'll be important to improve the level and fight to win a trophy. But I repeat, to win a trophy now is very difficult."

Conte reached successive FA Cup finals during his two-season stint at Chelsea, overcoming Manchester United in the latter in 2018.

The Italian is hoping to reach Wembley Stadium for a third time this campaign, but implored his side to show greater consistency if they are to end the club's wait for silverware.

"I'm not desperate but you know very well I want to win," he added.

"But I'm not desperate or it would be very hard to continue. For sure it's a great competition and previously I was lucky to reach the [FA Cup] final two years in a row. 

"I'd like to continue this tradition for Tottenham, especially for my players, especially the fans and the club, not only for me.

"But you know this trophy is not simple or easy, and tomorrow we have to face Middlesbrough, a tough game. Middlesbrough eliminated Manchester United from this competition. 

"I want to see continuity in the performance and result of my players. We need continuity to show that in defeat we are learning something more.

"Also I want to celebrate the game between Chelsea and Liverpool yesterday, it was a great, exciting game to watch. 

"This also underlines how difficult it is to win trophies in this country. It was amazing for me and all the people in other countries to watch this game. 

"Great congratulations from me to Chelsea and Liverpool, the players, the coach, for the fans, for the total environment it was a fantastic advert for football. I think that England has to be proud about this."

Pep Guardiola admitted Everton should have had a penalty for handball against Rodri in Manchester City's win at Goodison Park on Saturday.

Phil Foden struck eight minutes from time to seal a 1-0 victory for the leaders that moved them six points clear at the top of the Premier League.

Everton were denied the chance for a late equaliser from the penalty spot when neither referee Paul Tierney nor VAR felt Rodri should be punished for the ball striking his arm in the City box.

After the match, Guardiola felt the decision likely went in his side's favour due to offside in the build-up, but the Premier League clarified that the penalty was not awarded simply because there was insufficient evidence to show the ball struck Rodri below the level of his armpit, which is used as a cut-off point for handball.

Everton reportedly lodged a complaint with the league over recent refereeing decisions after boss Frank Lampard was left furious following the City defeat.

While Guardiola dismissed the idea that the decision could have lasting consequences for the season, he accepted Everton were unfortunate.

Speaking ahead of City's FA Cup clash with Championship side Peterborough United, Guardiola said: "Can this episode affect a whole season? I will review a lot of incidents. It looks offside for Richarlison; if it's not offside, it's a penalty."

Guardiola's men meet Peterborough on Tuesday aiming to reach the quarter-finals of the FA Cup for the fifth time since he took over as manager in 2016.

Goalkeeper Zack Steffen will miss out through injury, but Oleksandr Zinchenko is set to play after being an unused substitute against Everton.

Guardiola said it would be a good chance for the Ukraine international to "show the reason why he is here", adding he was a "magnificent player" who has remained committed amid the crisis in his homeland following Russia's invasion.

The City manager also paid tribute to Marcelo Bielsa, who left as Leeds United boss on Sunday following a dreadful run of results that culminated in a 4-0 home defeat to Tottenham.

"I'm so sorry for him," he said. "His legacy is there in the Leeds city, the club, the players. His influence is massive.

"Unfortunately, the manager goes by results and, lately, it was not good. The game he has played for three, four seasons in Leeds was spectacular to watch and of course, I wish him all the best.

"It will be a loss to Leeds and his players. As a person, he's not different to anyone. Results dictate our future."

Jurgen Klopp is heading towards becoming the "best Liverpool manager just for what he has achieved", according to former Reds striker Robbie Fowler.

The German boss added the EFL Cup to his growing list of trophies after Liverpool overcame Chelsea on Sunday in the highest scoring penalty shoot-out between two English top-flight teams.

That was Klopp's 10th crown of his managerial career, winning five with Dortmund and adding his fifth with Liverpool, who have triumphed in the Premier League, Champions League, UEFA Super Cup, Club World Cup and EFL Cup during his tenure.

Victory over Thomas Tuchel's European and world champions also kept the Reds in the hunt for an unprecedented quadruple.

Liverpool sit six points behind Premier League leaders Manchester City, who have played a game more, face Norwich City in the FA Cup fifth round on Wednesday and are 2-0 up at the halfway point of their Champions League last-16 tie with Inter.

Fowler, who scored 120 times for the Reds between 1993 and 2001, believes that Klopp will soon claim the title of Liverpool's greatest manager if he can add a few more trophies to his cabinet.

Asked whether Klopp is potentially the Reds' best ever boss, Fowler told Stats Perform: "Yes. It's hard to sort of sit here when you think of the great Liverpool managers of the past. 

"You're looking at Bill Shankly, who achieved so much for Liverpool. We're not even talking about Bob Paisley, who won the trophies that he won and was a great manager. 

"But I think Jurgen, potentially in a year or two if he gets a few more trophies, could conceivably be the best Liverpool manager we've seen just for what he has achieved. 

"Certainly, over the last four years he's been here, he’s got to two Champions League finals, a Europa League final and [won] a Premier League [title]. So, I think he's exceptional. 

"He's a manager I would have loved to play under because he ticks every box. I think we, as players, love managers who are technically or tactically very good.

"And we also love managers who are great man managers. And I think he ticks every box and is the epitome of an excellent and great manager."

It is not uncommon for second-choice goalkeepers to be given minutes in the early rounds of cup competitions, only for the number one to return when it comes down to the crunch.

Yet for Kepa Arrizabalaga, that will almost certainly not be the case.

Signed in 2018 from Athletic Bilbao for £71.6million (€80m), which is still a record fee for a goalkeeper, Kepa undoubtedly struggled in his first few seasons at Stamford Bridge.

Indeed, Kepa's form was so worrying that Chelsea, then managed by club great Frank Lampard, decided to sign Edouard Mendy from Rennes in 2020, just two years after shelling out that record-setting fee.

Yet since Thomas Tuchel came into the club, Kepa has been given a new lease of life.

While Mendy has solidified his place as the number one, Kepa has stepped up when called upon.

The nervous, shaky youngster has made way for a player who once again seems confident in his own ability and his right to play for the European champions.

With Mendy staying as the first choice in the Premier League and Champions League, for now, Kepa has nailed down a starting spot in the domestic cup competitions, and looks set to start against Liverpool in the EFL Cup final on Sunday.

Should he turn in another match-winning display, as he did in the UEFA Super Cup last year, then Tuchel may well have a decision to make on just who is his first choice after all.

What went wrong?

Kepa's move to Chelsea came in the same window that Liverpool had splashed out on Alisson, and there was plenty of expectation on both goalkeepers.

But while Alisson thrived under the pressure, going on to help Liverpool win the Champions League and then the Premier League a year later, Kepa crumbled.

The Spaniard also made headlines when he refused to be subbed off before a penalty shoot-out in, ironically, the EFL Cup final. Maurizio Sarri's side lost to Manchester City.

Across 36 league appearances that season, Kepa conceded 39 goals. Eight of these came from shots outside the box, with only five goalkeepers conceding more long-range efforts. His overall save percentage was 67.77, ranking him 15th in the competition.

Another way to assess the quality of Kepa's shot-stopping is by using the expected goals on target (xGOT) model to calculate the number of goals Kepa actually prevented. xGOT measures not just the quality of a chance (xG) but the quality of the attempt itself.

Kepa's Premier League xGOT figure for 2018-19 was 37.1. Minus the 39 goals he conceded, Kepa essentially allowed in just over two more goals than the numbers would suggest (-1.9).

In comparison, Alisson finished the season having prevented 5.5 goals in the league through the quality of his saves, while West Ham's Lukasz Fabianski, for example, had an outstanding figure of 12.9. 

Yet it was in 2019-20 that Kepa's form truly dropped off. He conceded 47 times from 33 league appearances, with only seven goalkeepers allowing more goals. His save percentage of 53.47 was the poorest in the league, out of shot-stoppers to play at least 10 times, while his goals prevented figure was -10.7 (including penalties, but excluding own goals).

Chelsea claimed a top-four place and reached the FA Cup final, yet it was Willy Caballero, not Kepa, who helped them get to a Wembley showdown and, at the start of 2020-21, they drafted in Mendy from Rennes.

Turning point

Things hardly improved for Kepa at the start of 2020-21. Across the Premier League season, no goalkeeper made more errors leading to goals than the Spain international, who committed three such mistakes in just seven appearances.

All of those mistakes came in his first three league appearances of the season, and he did not feature again in the top flight under Lampard, next playing in February. He made four saves, including an impressive stop from Joe Willock late on, as Tuchel's team defeated Newcastle United 2-0.

That, perhaps, was the start of Kepa's resurgence. Chelsea again reached the final of the FA Cup, and again lost - this time to a Youri Tielemans stunner for Leicester City - but Kepa played in all six of those cup matches.

However, the true turning point came in August's Super Cup. Tuchel's side triumphed 6-5 on penalties over Europa League winners Villarreal following a 1-1 draw in Belfast, and Kepa was the hero.

In contrast to that 2019 EFL Cup final, Kepa was the goalkeeper brought on specifically for penalties this time, and he denied Aissa Mandi and Raul Albiol to ensure victory.

Back at his best?

Perhaps Kepa will need to move on to be a first-choice goalkeeper once again. After all, at 27 he can no longer be counted as a youngster, and as it stands Mendy is still Tuchel's number one.

Though Kepa will get his chance in Sunday's EFL Cup final, surely, to help Chelsea claim a third trophy of the season, following the Super Cup and the Club World Cup, in which he featured in the semi-final.

Since that Super Cup success, Kepa has been a consistent performer. In his 13 games across all competitions, he has conceded just eight goals, keeping six clean sheets.

Those eight goals have come from an xGOT of 18.5, meaning Kepa's "goals prevented" figure is now way into the black, at 10.5.

In fact, that figure is the best of any goalkeeper in Europe's top five leagues in all competitions, proving just how much Kepa has come on over the course of the last year.

Mendy, in comparison, has stopped just over three goals with his saves, while Kepa also holds a better save percentage (83.7 to Mendy's 77.4), and he has established himself as worthy competition.

It may not be what Chelsea had in mind when they paid that world record fee in 2018, but if he helps them to another piece of silverware on Sunday, it would be hard to argue he is not starting to prove his worth.

Graham Potter is relishing the chance of going up against Cristiano Ronaldo, and the Brighton and Hove Albion boss believes the Manchester United star's troubles have been overblown.

Ronaldo has not scored or provided an assist since December 30, a run of six matches across all competitions.

The 37-year-old has created just six chances for team-mates across that run, while he has missed both of the big chances (defined by Opta as an opportunity from which a player would be expected to score) that have come his way.

He has only registered an expected goals (xG) above 1.0 in one of those matches, against Middlesbrough in the FA Cup (1.6). Ronaldo missed a penalty in normal time before United crashed out in a shoot-out.

Indeed, he has only recorded an xG of over 0.5 on one other occasion across the last six games, suggesting the chances that are coming his way are not the best, or he is perhaps taking on shots that would be unlikely to result in a goal.

This is further reinforced by the fact Ronaldo has got just seven of his last 23 attempts on target.

Potter, however, does not buy the suggestion that Ronaldo is out of form.

"You run out of superlatives in terms of what he's achieved in his career and the player that he is," Potter, who is about to reach his 100th league game in charge of Brighton, told a news conference.

"He's had an absolutely amazing career, world-class, it's out-of-this-world class. There's nothing else to say with that.

"Too often we zoom into individuals and forget it's a team game. Sometimes when the team isn't scoring, the person at the front of the pitch gets the zooming in.

"From what I've seen, you still see the quality he has and the quality he brings to the group and the team.

"I've never played against him, we're looking forward to going there and pitting our wits against one of the best players of all time."

Ralf Rangnick has lamented United's profligate finishing at one end, and sloppy defending at the other.

He is right, though. United have been creating opportunities, mustering an xG of 23.3 since Rangnick's first game in charge on December 5, but they have scored just 17 times, giving them the third-largest xG-goals differential among all teams in Europe's top five leagues in that time (-6.3).

Potter is all too familiar with such a statistic, with Brighton having had an xG differential of -11.7 in the Premier League last season, having scored 40 goals from an xG of 51.7.

Brighton are still underperforming in that regard so far in 2021-22, but by only 3.8, netting 25 league goals from an xG of 28.8 so far.

However, his team have won 19 points away from home in the Premier League this season, with no side losing fewer on the road this term.

"Regardless of what the narrative around Manchester United is, you only have to look at the players that they have," Potter added.

"Going to Old Trafford in itself is a huge challenge because the crowd are so powerful there; the way they play, in a moment the game can completely change because they've got world-class players.

"The game is another test for us to see how our game has developed in as tough an away environment as you can get."

N'Golo Kante has insisted Chelsea "will go for every trophy" and is still hungry for success after winning the Club World Cup.

The Blues defeated Palmeiras 2-1 to win the competition for the first time in their history, having qualified after winning their second Champions League title last season.

Chelsea were fancied to push Manchester City and Liverpool all the way in the Premier League title race, though a top-flight charge now looks unlikely.

However, they have an EFL Cup final coming up against Liverpool at the end of February, while Thomas Tuchel's team remain in the FA Cup and the Champions League. They will face Luton Town and Lille respectively in the next rounds of those competitions.

With a first trophy of the season under Chelsea's belt, Kante – who also counts two Premier League titles and the World Cup among his honours – is eager for more.

"We know there are many more important games coming with the final of the Carabao Cup, we're still in the Champions League, we have to do well in the Premier League and the FA Cup is coming," Kante told reporters.

"So many great things are ahead of us. We hope we will enjoy many more nights like these. I don't know what we can achieve, but what we want is to get the best out of our team so we compete for everything. We will go for every trophy."

Kante also believes Chelsea proved how much the Club World Cup success meant to them by playing a strong team, despite the tournament being played mid-season.

"We took it very seriously," Kante continued. "For many of the players, we've never played this tournament, the club had never won it and to have the privilege to play it and win it is very special. It's a very nice feeling.

"It's the first time for the club and we're happy to be part of that, to have done it. Also, for us, it is the following of the success of the Champions League.

"This is special. It's a nice moment, we're all together and it's another trophy."

Despite the success this Chelsea squad has achieved over the past year, Callum Hudson-Odoi explained that, for young players like himself, there is still much to accomplish before he or his team-mates can be considered as club greats.

"I don't feel like a legend at all," Hudson-Odoi said. "At the end of the day I'm young, I've got a long way to go.

"I'm delighted to win trophies. When you win trophies it is a big feeling. You keep adding and adding to the cabinet and it's nice but you can't say you're a legend at 21.

"It is too, too early to say that. There is a lot more to come, hopefully. We keep pushing and keep going and at the end of the day we keep creating more history for the club and enjoy it while we can."
