Antonio Conte believes Tottenham have taken "a step forward" this season, despite their final chance of silverware being ended by Milan on Wednesday.

Spurs were unable to overturn a 1-0 deficit from last month's Champions League last-16 first leg as they played out a 0-0 draw in the return fixture at Tottenham Hotspur Stadium.

Despite knowing they needed a goal to stay in the tie, Spurs failed to muster a single attempt on target in the first half and only seriously troubled Mike Maignan once all game.

The Milan goalkeeper produced a fine save to keep out Harry Kane's late header, which came after Cristian Romero was sent off for two bookable offences.

It means Tottenham's wait for a trophy of any sort will stretch into a 16th year, with a top-four battle in the Premier League all they have to fight for this campaign.

But after failing to qualify for the Champions League in the past two seasons, and struggling in the Europa Conference League last year, Conte is focusing on the positives.

"If I have to see a positive situation, it's that we had a step forward," he told BT Sport. "We played in the Conference League last year and weren't able to get out of the group. 

"Now we took a step forward but it is not enough and if we want to be competitive, we have to fight."

Spurs, eliminated from the FA Cup by second-tier Sheffield United last week, have failed to net in three straight games for the first time since between April and May 2019.

They finished with an expected goals (xG) value of 0.45 in their second leg against Milan, compared to 1.4 for their opponents.

"That is the third game in a row that we were not able to score," Conte said. "I think the game was in the balance. I think we can do much better offensively. 

"I speak about the whole team, not only those who play in the front half of the field. We can do much better.

"I can't tell anything negative about the commitment of the players. They gave everything from the start to the end."

Wednesday marked the first time Tottenham have been held to a goalless draw at home in any competition since doing so against Swansea City in September 2017, a run spanning 147 games.

Tottenham, bar Kane's late header, failed to offer any sort of attacking threat and were booed off both at half-time and full-time by their supporters.

"In our mind we wanted to put pressure on them with intensity, but in the first half we found it difficult offensively," Conte said of Spurs' tentative approach.

"We found space to receive the ball and create one-v-ones, but we struggled. We felt a bit of pressure. I think they need to play regularly this type of game to try to improve.

"I think everybody wants to go to the next round. In the first game we lost a good chance. Milan were without important players then, like us.

"We have to continue to work. We have another game that we have to recover for. We have to try to reach the best possible position at the end of the season."

Spurs return to action on Saturday with a home match against Forest in the Premier League, before travelling to Southampton in their final game before the international break.

Stefano Pioli warned his Milan players they cannot just sit back and defend their 1-0 first-leg lead at Tottenham in the Champions League last 16 on Wednesday.

Pioli's men take a narrow advantage to the Tottenham Hotspur Stadium for the second leg after Brahim Diaz's first goal since October put them ahead at San Siro.

Milan will return to the Champions League quarter-finals for the first time since the 2011-12 season if they avoid defeat, though Pioli cautioned his players not to sit back and just focus on defending on Wednesday.

"Tomorrow is the match of personalities," Pioli told reporters at his pre-match news conference. "Our opponents are formidable from an offensive point of view, they will play with great intensity.

"We must be prepared to control the game more. We have a very small advantage but we cannot think of managing it. We must attack and play with intensity."

Pioli is expecting a great atmosphere in north London, though is confident his team can focus on the task ahead of them, saying: "We expect a loud stadium, just like San Siro was.

"But the crowd doesn't score goals. We arrive with confidence, enthusiasm and determination."

Spurs have been boosted ahead of the game by the return of head coach Antonio Conte, who had been recovering in Italy after undergoing gallbladder surgery.

Pioli acknowledged the importance of Conte being on the sidelines for Spurs, and feels his team will have to match the Premier League side's intensity to secure their progression.

"Antonio Conte's presence on the bench will be an added value for Tottenham," Pioli added. "But beyond Conte, we will find a highly prepared and motivated opponent.

"Both teams want to go through this round. Tottenham will probably try to attack more than at San Siro. We have to watch out for particular moments."

Antonio Conte's recent absence from Tottenham due to recovery from gallbladder surgery did not change his mind about his future at the club amid reports of a contractual impasse.

Conte was back in the hot seat on Tuesday as Spurs held their pre-match press conference before Wednesday's Champions League last-16 second leg against Milan.

Spurs revealed Conte was set for a period of leave on February 1 after a sudden illness required the emergency removal of his gallbladder.

He returned to work just eight days later but was then signed off again on February 16, with Conte acknowledging he underestimated how long his body needed to recover.

The visit of Milan will be Conte's first game back at the helm, assuming control again from Cristian Stellini, but it comes following strong rumours claiming he will not be staying beyond the end of the season when his contract ends.

Conte sounded committed upon his return but did not directly discuss his future and his comments hinted at there being no movement.

"This type of situation can happen and I discovered after the surgery that many of my friends had the same surgery," he told reporters.

"This was emergency surgery, not planned, and that's very different. Previously a lot of sad news happened and when [the doctors] told me that I had only [needed] surgery, for this reason I was happy, because you never know what could happen.

"This doesn't change my mind. Now, I repeat that I have to stay with the players and breathe the atmosphere of the training ground."

Results for Spurs have been mixed over the past five weeks or so since Conte initially took time off.

The lowest moment, however, came last week when Championship side Sheffield United knocked them out of the FA Cup.

Conte wanted to return after that embarrassment for Spurs but was blocked by doctors.

"I wanted to come back after the game against Sheffield United but the doctors stopped me," he continued.

"They said, 'you have to listen to us and wait two days more and come back to London on Sunday for the game against Milan'. But honestly, I wanted to come back early."

Despite Spurs' lack of on-pitch consistency and Conte's own off-field frustrations, he appeared to be in high spirits as Tottenham look to overturn a 1-0 first-leg deficit.

He added: "[Monday] was positive. My feeling was really good. It's important for me to work with my players and the staff and prepare for the games.

"From afar I tried to stay very close with my players using video. To be present is totally different and for this reason I have to say thanks to my whole staff. They did a really good job and the players to stay for three weeks without the manager wasn't easy.

"Now I'm back and I'm really happy. We want to go to the next round and for tomorrow I hope to feel an amazing atmosphere in our stadium. Our fans give us a major boost and we're playing against the team that won the league in Italy last season."

Son Heung-min also recognised the significance of Conte's return from the players' perspectives, with the former Inter coach bringing with him his trademark boisterousness.

"It's important," he said. "I'm glad that the manager is sitting next to me.

"He brings good energy to the team. When the boss isn't here it's different. We could feel that energy and his passion on the touchline [in training on Monday]. We'll feel more comfortable."

Antonio Conte will return to Tottenham on Sunday ahead of the Champions League clash against Milan.

The Spurs head coach remained in Italy following the first-leg last month, a 1-0 defeat at San Siro, to recover from gallbladder surgery.

In his absence, Spurs secured back-to-back 2-0 victories in the Premier League against West Ham and Chelsea, resulting in Conte's nomination for the Manager of the Month award for February despite not being in the dugout.

However, Spurs also suffered a shock exit from the FA Cup at the hands of Sheffield United on Wednesday and require a turnaround in the second-leg against Milan at Tottenham Hotspur Stadium next week to qualify for the quarter-finals of the Champions League.

Conte will be back for that clash, as confirmed by his assistant Cristian Stellini in Friday's press conference ahead of the Premier League trip to Wolves.

"Antonio is fine, he cannot wait to come back. The medical department decided to leave Antonio's comeback until Sunday, after the match at Wolves," he told the club's website.

"Because that is one month after the surgery. That was the agreement from the doctor who did the surgery and our medical department."

Tottenham currently sit fourth in the top-flight, four points ahead of Newcastle United, though the Tyneside club have two games in hand.

Picking the right time to bring Son Heung-min off the bench allowed Tottenham to kill the game off against West Ham, according to stand-in boss Cristian Stellini.

Son was benched for Sunday's 2-0 victory, as Spurs battled through not having Antonio Conte on the touchline to see off their London rivals and move into the top four of the Premier League.

Richarlison was preferred to Son in the starting XI, but after Emerson Royal had given Spurs the lead, the South Korea international came off the bench to slot home a second and boost his side's top-four hopes.

Son has now scored four goals as a substitute in the Premier League this season, twice as many as any other player, despite only making two appearances off the bench.

Deputising for Conte, who is back in Italy recovering from emergency gallbladder surgery earlier this month, Stellini feels choosing the right time to introduce Son helped Spurs to put the game to bed as he punished the space the Hammers left while pursuing an equaliser.

"Son stayed on the bench, the moment was important," Stellini told Sky Sports. "And it was the moment for Son.

"With the space, Son is an amazing player and we try to use him in this way. It was a good idea.

"Son has a goal so we are happy for him. He has to stay calm and produce his best performance.

"At the moment he is not 100 per cent so we have to manage him."

While he was frustrated with starting on the bench, Son understood the decision and was delighted to come on and help his team, saying: "Nobody wants to sit on the bench but it's a decision you to have accept.

"The pass was really good and my first touch helped to make the goal.

"I tried my best to help the team. I got the chance and I was happy to score."

After Stellini took charge of the 1-0 victory over Manchester City, Conte returned from his surgery for the defeats at Leicester City and Milan. However, the former Chelsea boss returned to Italy to recover further having "underestimated the procedure."

Son praised the work Stellini and his fellow coaches had undertaken in Conte's absence, stating: "If he's [Conte] not here, it's really sad. Sometimes we forget football is not the most important thing. We hope that the gaffer is coming as soon as possible.

"The coaching staff did an amazing job and gave us really good confidence and tactics."

Conte still has an influence on proceedings even in his absence, with Stellini explaining: "Conte sent some texts to the bench and they transferred it to me.

"He is good, he is fine and can be involved in the game so that is fine. Sometimes I want to do things and I ask him and he allows me.

"[It is a] big responsibility but with the responsibility, you have to grow a bit.

"I'm happy because I have Ryan Mason with me to help me a lot and all the staff work hard and we push ourselves in another level to try and cover the gap."

Son Heung-min returned to scoring form to help Tottenham claim a 2-0 victory over West Ham, propelling them into the Premier League's top four.

With Antonio Conte back in Italy recovering from emergency gallbladder surgery earlier this month, stand-in head coach Cristian Stellini was again charged with leading Spurs at the Tottenham Hotspur Stadium.

Stellini made it two wins from two games in temporary charge as substitute Son sealed the points with his first league goal since January 4 after Emerson nosed Spurs ahead in the 56th minute.

West Ham's defeat leaves them in the bottom three while Spurs, who lost heavily to Leicester City last week then went down to Milan in the Champions League, leapfrogged Newcastle United into fourth place.

There were warning signs for Spurs when Jarrod Bowen blasted wide in the opening minute, though a refereeing decision was the main talking point from a sluggish first half.

Eight days on from Tomas Soucek getting away with a similar incident against Chelsea, team-mate Thilo Kehrer was perhaps fortunate not to concede a penalty when Richarlison's pass struck his outstretched arm.

Pierre-Emile Hojbjerg and Richarlison were denied by Lukasz Fabianski before Cristian Romero headed over, with Spurs keeping up the pressure after the restart when Harry Kane went close.

That pressure told before the hour – Emerson coolly slotting into the bottom left corner after combining with fellow wing-back Ben Davies.

Bowen almost found an immediate response for West Ham but Fraser Forster was equal to his snapshot.

And West Ham's hopes of a comeback were all but dashed when Son, who had lost his place in the starting XI to Richarlison, finished calmly after linking up with Kane.

Antonio Conte has acknowledged he underestimated the seriousness of "sudden and serious emergency" that he faced after the Tottenham boss decided to take a break until he has fully recovered.

Italian Conte underwent gallbladder surgery at the start of this month, having suffered severe abdominal pain.

The Spurs head coach was back on the touchline for a 4-1 Premier League defeat at Leicester City last weekend before overseeing a 1-0 defeat at Milan in the first leg of the Champions League round of 16 tie on Tuesday.

Tottenham on Thursday revealed the 53-year-old has remained in Italy at his family home to recuperate and Cristian Stellini will once again take charge of the first team in his absence.

Conte knows he returned too soon and knows he must take time out after a routine post-operation check in his homeland this week.

He wrote on an Instagram story: "My great sense of responsibility towards the club, the players the staff and the fans brought me to anticipate my comeback. Sadly I underestimated the procedure, which wasn't a routine operation but a sudden and serious emergency.

"My body has suffered [for] my impatience and now I am forced to stop until my entire recovery.

"Those who know me understand what a burden this is for me, but it is necessary. Come on you Spurs."

Tottenham said in a statement: "Following a routine post-operation check in Italy yesterday, Antonio Conte will remain at his family home to further and fully recover from his recent gallbladder surgery.

"Health is the most important consideration and everyone at the club wishes him well. Cristian Stellini will assume first-team responsibility."

Fifth-placed Tottenham will attempt to get back on track when they face West Ham at home in a London derby on Sunday.

Antonio Conte is taking a fresh break from his Tottenham duties to continue his recovery from gallbladder surgery.

The head coach had the organ removed at the start of the month after experiencing severe abdominal pain and took a short break from Spurs to begin his recovery.

Conte returned to duties on the training pitch last week before the 4-1 defeat to Leicester City in the Premier League on Saturday.

He then also took charge for the 1-0 loss to Milan in the Champions League on Tuesday.

However, Conte has since had his recovery progress checked out, and it has been decided he will need more time away from frontline work.

Tottenham said in a statement on Thursday: "Following a routine post-operation check in Italy yesterday, Antonio Conte will remain at his family home to further and fully recover from his recent gallbladder surgery.

"Health is the most important consideration and everyone at the club wishes him well. Cristian Stellini will assume first-team responsibility."

Stellini is Conte's assistant and led the team for their 1-0 win over Manchester City on February 5, while Conte was at home in Turin.

Tottenham have two Premier League home games coming up on successive Sundays, facing West Ham this weekend and Chelsea seven days later.

They then travel to Sheffield United in the FA Cup and to Wolves in the Premier League, before Milan head to the Tottenham Hotspur Stadium for the second leg of their last-16 European tie on March 8.

Conte's team sit fifth in the Premier League, two points behind a fourth-placed Newcastle United side who have a game in hand.

Antonio Conte insisted Tottenham could turn around their first-leg deficit after a 1-0 loss at Milan in the Champions League.

Brahim Diaz made an early breakthough, scoring in the seventh minute at San Siro when he nodded in from close range after Fraser Forster made saves from the Spaniard and Theo Hernandez.

Milan could have stretched their lead in the second half but spurned chances, giving Tottenham reasonable grounds for optimism ahead of the March 8 second leg in London.

Former Inter boss Conte wants the Tottenham Hotspur Stadium to radiate the same type of atmosphere Spurs experienced at San Siro, believing that could help Spurs through to the quarter-finals.

He told BT Sport: "You have to play two games. It was a fantastic atmosphere. I know San Siro, and I know the difficulty to play in this atmosphere.

"For sure in the second game we have to play in our stadium and for sure all the fans will create the right atmosphere to push us to overcome the Milan obstacle."

His injury-hit team were crushed 4-1 at Leicester City in the Premier League on Saturday, and Conte was without Pierre-Emile Hojbjerg due to suspension for Tuesday's last-16 first leg in Italy.

Pape Sarr and Oliver Skipp paired up in central midfield, with Yves Bissouma and Rodrigo Bentancur sidelined due to long-term injuries, and Conte liked what he saw, to a point.

"I think it was better today – high intensity, and I think we played against a good team. Don't forget Milan last season won the league in Italy," Conte said.

"I think that to concede the first goal, we can do much better. We conceded a goal after maybe only five minutes.

"Then we tried to lead the game, we tried to create situations to score, but I think Milan defended very well. We had chances to score, but at the end we are talking about a defeat, a loss."

He said of Sarr and Skipp: "I'm really satisfied for both players. They played a really good game and showed the trust that we have in them, they repaid this.

"Don't forget we now have three midfielders and we have to continue maybe to the end of the season with these three midfielders, and to have this type of performance from Skippy and Pape Sarr makes me more relaxed because I know I can count on them 100 per cent.

"And then we have Pierre Hojbjerg who for us is a key player."

Skipp said of his first start in the competition: "It wasn't the result we wanted, but there's a second leg to come and we're still right in the game.

"There were things we could have done better, things we did well. It was nice to gain the manager's trust."

Antonio Conte urged Tottenham to find "stability" as his side search for a response to their Premier League hammering when they face Milan in the Champions League on Tuesday.

Spurs overcame second-placed champions Manchester City in the English top flight but were stunned 4-1 by strugglers Leicester City a week later on Saturday.

Tottenham's next challenge sees them go to out-of-form Milan in the Champions League last 16 and Conte called on Spurs to recover at San Siro.

"I think we will get this answer tomorrow; it will be much easier finding the right answer tomorrow," Conte said at his pre-match press conference when asked why Spurs have struggled.

"Trying to forecast the future today is impossible. I think we are lacking that stability, which is always crucial. You need stability, you need consistency, you can't have these ups and downs.

"I am trying to work on this and focusing on not having ups and downs. England is not like Italy, the Premier League is not like Serie A, we have different cultures in these two leagues.

"In England, it is much more difficult to be focused and stay focused for every game. In Italy, it is easier.

"This stability is lacking this year. I always talk about it with my players. It is tough to keep concentration, it is challenging to stay focused all the time.

"We are working on that. Playing under pressure all the time is good for some players and bad for others. Sometimes players feel motivated other times feel so much under pressure that they can't perform.

"Maybe for a period they have a good performance, and then they collapse all of a sudden if they feel too much pressure."

Head coach Conte said his side are "working on" dealing with the increased pressure, though injuries are another crucial factor to Tottenham's success.

"We want to make our players more resilient but there are also external factors like injuries for very important players for us," Conte said after losing Rodrigo Bentancur, Yves Bissouma and captain Hugo Lloris to injury.

"Those injuries influence the team, influence the growing evolution of the league.

"You can be prepared for everything, you can be a tactical man, good strategies, good line-ups, you can have high-quality players but then if those high-quality players get injured then you need to change things. Every manager wishes to have the best players available."

Milan ended a seven-game winless run across all competitions with a 1-0 league victory over Torino on Friday to somewhat ease the mounting pressure on coach Stefano Pioli.

However, an unfavourable result in Europe will only add to calls for the removal of Pioli, who ended Milan's 11-year wait for the Scudetto last season with triumph in Serie A.

Conte believes managing in England and Italy comes with many different challenges and pressures, given his home country consider football not only a sport but as "war".

"I sometimes think also in my previous experience with Chelsea, the pressure is different between Italy and England," he added. 

"In Italy, you speak about football from Monday and you finish on Sunday. You speak only football and then you have a lot of television that speaks football and puts a lot of pressure.

"You are born in this way and you grow in this way, with this pressure, and you are used to living with this type of situation.

"In England, I think that there is an atmosphere that brings to enjoy football without a lot of pressure, because football is a sport and in Italy sometimes football is not only a sport, it is a war between the teams and the fans."

Stefano Pioli is relishing Tuesday's meeting with old foe Antonio Conte as Milan prepare to host Tottenham in their first outing in the Champions League knockout stages since 2014.

Milan finished second to Chelsea in Group E to progress to the last 16 for the first time since the 2013-14 season, when they were hammered 5-1 on aggregate by Atletico Madrid.

Conte's Tottenham stand between Milan and a spot in the last eight, with the former Juventus and Inter boss one of five Italian coaches still present in the competition.

Conte has won eight of his last nine games against Milan (L1) in a run dating back to 2013, and he joins Pioli, Inter's Simone Inzaghi, Napoli's Luciano Spalletti and Real Madrid's Champions League specialist Carlo Ancelotti on an impressive list of Italian bosses to escape the group stage.

Asked who was the strongest of those coaches at Monday's pre-match press conference, Pioli said: "Ancelotti is a symbol but so are Conte and Spalletti. 

"There are lots of good coaches, we have a good school and important characteristics. 

"Conte is a great coach and one of the few colleagues who called to congratulate me on the Scudetto last season.

"It will be a difficult challenge, inevitably it will be like this for a quarter-final place. A week ago they beat Manchester City. It will be a great game that we will have to play well."

Despite Milan's absence from the latter stages of the competition in recent years, only Real Madrid (14) can better the Rossoneri's tally of seven European Cup/Champions League titles.

Asked whether Milan's illustrious history in the competition could present a psychological barrier for Spurs, Pioli said: "I can't know what our opponents are experiencing, I know what we feel. 

"We are highly motivated and it's normal. We only think up to Tottenham. Winning the Champions League is a dream today but it's useless to think about it now."

With Milan 18 points adrift of Serie A leaders Napoli and suffering defeats in the Coppa Italia and Supercoppa Italiana last month, their Champions League tie against Spurs will go a long way to dictating whether their season is deemed a success.  

Speaking to Sky Sport ahead of his press conference, Pioli described the tie as the most crucial occasion of his career.

"They will be the two most important matches of my career, having never played in a Champions League round of 16. We have prepared ourselves in the best possible way," he said.

"Our aim is to play with more pace and intensity, you can't ignore that in these competitions. We have prepared ourselves to be up to it."

The last 16 of the Champions League gets underway on Tuesday with two potentially fascinating encounters.

Milan host Tottenham in the Rossoneri's first Champions League knockout game since the 2013-14 season, while two of the favourites in this year's competition, Paris Saint-Germain and Bayern Munich, face off in the French capital.

Neither Milan nor Spurs come into their first leg in the best form, with Stefano Pioli's side getting their first win in eight games on Friday against Torino, while their English opponents were thrashed 4-1 by Leicester City.

PSG are also faltering, having lost 3-1 at Monaco at the weekend, leading to fan protests and Presnel Kimpembe having to calm them down through a megaphone.

Bayern will hope to add to the problems of Christophe Galtier's men, who seem likely to be without Kylian Mbappe, but Julian Nagelsmann admitted his own players are "not in the flow" in spite of their 3-0 win against Bochum on Saturday.

Stats Perform has taken a look at some Opta numbers ahead of the first pair of Champions League knockout games.

Milan v Tottenham

This will be the fifth competitive meeting between Milan and Tottenham, with the Premier League side unbeaten across each of the previous four (W2 D2).

They last played each other in the 2010-11 campaign at the same stage of the Champions League. Spurs won 1-0 on aggregate, with Peter Crouch scoring the only goal of the tie.

Spurs boss Antonio Conte has won eight of his last nine games as a head coach against Milan (L1), between 2013 and 2021. Indeed, he has seen his side win and keep a clean sheet in each of his last three trips to face the Rossoneri away from home (2-0 in 2014, 2-0 in 2019 and 3-0 in 2021 – all in Serie A).

Conte will be looking to win consecutive away games in the Champions League for just the second time in his managerial career, having last done so in the 2012-13 campaign when he was at Juventus (1-0 v Shakhtar Donetsk and 3-0 v Celtic).

Olivier Giroud has been directly involved in six goals for Milan in the Champions League (four goals and two assists) – the last player with more in a single campaign in the competition for the club was Zlatan Ibrahimovic in the 2011-12 season (nine – five goals and four assists).

Ivan Perisic has three assists in five appearances for Spurs in the Champions League, already his joint-most for a club among the four he has played for in the competition: three in 10 games for Bayern, one in 20 for Inter and none in 11 for Borussia Dortmund.

The three players to have recovered possession most often in the middle third of the pitch in the Champions League this season all play for either Milan or Spurs: Rodrigo Bentancur (34), Ismael Bennacer (32) and Pierre-Emile Hojbjerg (31), though Bentancur will be missing after suffering a season-ending knee injury at the weekend.

Paris Saint-Germain v Bayern Munich

PSG have faced Bayern on 11 previous occasions, with all of them coming in the Champions League. The teams are separated by just one victory (six for PSG and five for Bayern), while they have scored the same number of goals (15 each).

Among teams who have faced Bayern on 10+ occasions in the Champions League, PSG are the team with the highest win percentage against them (55).

Bayern won all six of their group games this season, scoring 18 goals and only conceding twice. The only previous occasion in which they won their first seven matches of a Champions League campaign was in the 2019-20 campaign, when they had a 100 per cent record (11/11) in the competition.

PSG have only failed to score in one of their last 32 home games in the Champions League (averaging 2.6 goals per game), though the exception was in a 1-0 defeat against Bayern in the 2020-21 quarter-final second leg.

Joshua Kimmich has won 76 per cent of his matches for Bayern in the Champions League (50/66). Among all players to make 50+ appearances in the competition, he is the only player to have featured on the winning side in more than three quarters of his games.

Since the start of the 2017-18 season – his first at PSG – Mbappe has been directly involved in 57 goals in 50 appearances in the Champions League (34 goals and 23 assists). Indeed, he is the only player with both 20+ goals and 20+ assists during this period. He will be a big miss should he not recover from injury in time, though he did train on Monday.

In the last two Champions League campaigns, only Robert Lewandowski (21), Mbappe (20) and Mohamed Salah (18) have been directly involved in more goals than Leroy Sane (17 – 10 goals, seven assists).

Lionel Messi has generated more shots following a carry (moving five or more metres with the ball) than any other player in the Champions League this season (14 – six shots and eight chances created).

Cristian Stellini has questioned the mentality of Tottenham's players and accepts "something has to change" after a 4-1 loss at Leicester City.

Spurs failed to build on last weekend's 1-0 win over Manchester City as their hopes of finishing in the Premier League top four suffered another setback.

Rodrigo Bentancur gave Tottenham the lead, but Leicester responded with goals from Nampalys Mendy, James Maddison and Kelechi Iheanacho before half-time.

Harvey Barnes added a late fourth at the King Power Stadium to inflict a fourth league defeat on Spurs in seven matches since the turn of the year.

Tottenham assistant Stellini, who took press duties despite Antonio Conte returning to the dugout following gallbladder surgery, was not pleased with what he saw on Saturday.

"To be consistent is a long process; it's a mental process," he said. "You have to be better mentally and better with the approach. After we scored the goal, something changed.

"We struggled a lot and we are disappointed for that. There's not an explanation because if you know what happened you can change this. 

"It happened last season, after we beat Manchester City we lost to Burnley. We are a team, and in the team something has to change, not individually. It's about the desire.

"It's about recovering the mental energy. After a game against City, maybe we used all the energy we had. To recover that is like a battle. You have to recreate the same energy."

Conte returned to Tottenham's training ground on Thursday, eight days on from undergoing surgery, but Stellini explained the head coach is still recovering.

"It's good for the club, the team and everyone to have Antonio back," he said. "He has to take it easy a bit. 

"He cannot use his energy 100 per cent and we have to give something more to cover the gap. We know we have to be more responsible."

Tottenham are two points behind fourth-place Newcastle United, who played out a 1-1 draw with Bournemouth later on Saturday and have a game in hand.

Conte's side host London rivals West Ham and Chelsea in their next two league games, but first is a Champions League last-16 first-leg tie away at Milan on Tuesday.

Tottenham missed the chance to climb into the Premier League’s top four as Leicester City humbled Antonio Conte's team 4-1 at the King Power Stadium.

Head coach Conte was back in the Spurs dugout having missed last week’s 1-0 win over Manchester City after undergoing gallbladder removal surgery.

But the Italian’s presence failed to inspire the visitors. Despite Rodrigo Bentancur's early strike putting Tottenham ahead, Nampalys Mendy equalised with his first Leicester goal, while James Maddison and Kelechi Iheanacho put the hosts 3-1 to the good at half-time.

Harvey Barnes completed a thumping victory, firing home with nine minutes remaining to move Brendan Rodgers' side six points clear of the relegation zone.

Tottenham broke through in the 14th minute when Ivan Perisic’s corner ricocheted kindly for Bentancur, who slotted into an open net from four yards. But Leicester turned the contest on its head with two goals in three minutes.

Mendy opened his account in emphatic fashion with a thumping 20-yard drive into the roof of the net after Spurs only half-cleared a corner.

The midfielder's strong challenge on the halfway line then released Iheanacho, who unselfishly laid the ball off for Maddison to slide home.

Iheanacho made it 3-1 in first-half stoppage time when he neatly bent a 20-yard shot into the far corner.

Spurs looked to respond after the break when Bentancur, who later limped off injured, tested Danny Ward from distance.

However, Leicester put the result beyond doubt nine minutes from time. Having been denied by VAR in the 70th minute, this time Barnes received the ball from Maddison before calmly threading past Fraser Forster into the bottom-right corner from 20 yards.

Antonio Conte has returned to work with Tottenham after undergoing surgery last week to remove his gallbladder.

Spurs announced last Wednesday the Italian coach had to go under the knife after complaining of "severe abdominal pain" linked with cholecystitis.

Conte missed Tottenham's 1-0 Premier League win over Manchester City last weekend, with assistant Cristian Stellini filling in.

The 53-year-old flew back from Italy to England earlier this week and oversaw training on Thursday ahead of this weekend's trip to Leicester City.

However, it has not yet been confirmed by Tottenham whether Conte will be in the dugout at the King Power Stadium on Saturday.

According to the United Kingdom's National Health Service (NHS), the procedure Conte underwent can take roughly a month to "return to your normal activities".

Tottenham, who are fifth in the Premier League, follow up their game against Leicester with a trip to Milan for the first leg of their Champions League last-16 tie on Tuesday.
