Ronald Koeman believes Barcelona demonstrated they are on the right track by overcoming an early setback to win 3-2 at Athletic Bilbao.

Inaki Williams raced clear to put the hosts, who had Marcelino in charge for the first time, in front inside three minutes of Wednesday's LaLiga clash.

However, Barca responded impressively, goals from Pedri and Lionel Messi putting them in front by the break before the latter increased their lead just after the hour mark.

Koeman had to endure a nervy finish after Iker Muniain's 90th-minute finish, but promised his squad will "fight until the last match" in LaLiga after moving up to third in the table.

"The final result is a bit short because we have been superior in many phases," Koeman said, having now recorded three away wins on the spin in LaLiga for the first time in his reign.

"They made it 1-0 and we did not have the defensive coordination, but then we controlled [the game].

"I am happy with the result and with how we have achieved it. We have deserved it. Winning because of our game and our opportunities.

"The teamwork has been phenomenal. We will fight until the last match. There is distance [to go], but we are on the right track." 

Messi will understandably dominate the agenda having scored twice, but Koeman was also quick to praise the performance of Pedri, who completed over 90 per cent of his attempted passes.

The teenage midfielder scored the equaliser, heading in Frenkie de Jong's cutback cross with goalkeeper Unai Simon out of position, while it was his backheeled pass that set up Messi to make it 2-1.

"Pedri is showing despite his youth that he is very mature," the Dutchman said in his post-match interview.

"Messi has always shown his desire but today also with goals. It is very important."

Messi's long-term future at Camp Nou may be unclear but his recent form has shown no lack of commitment to the cause; he has been involved in 10 goals in his last 10 games in all competitions.

Barca are next in action on Saturday, when they visit Granada.

Mauricio Pochettino was satisfied with the effort put in by his Paris Saint-Germain team against Saint-Etienne, but knows there are lots of improvements to make.

PSG laboured to a 1-1 draw in Pochettino's opening game in charge, with the former Tottenham boss having replaced Thomas Tuchel.

The Ligue 1 champions moved up to second thanks to Lille's defeat to Angers, but are three points behind leaders Lyon.

Saint-Etienne capitalised on Idrissa Gueye's mistake to take the lead, but Moise Kean's eighth league goal of the season cancelled out Romain Hamouma's opener.

Denis Bouanga hit the crossbar for Saint-Etienne after the break, while Kean snatched at a good chance and Angel Di Maria forced Jessy Moulin into action with what was PSG's only shot on target in the second half as the spoils were shared on Wednesday.

"I am happy with the efforts of the players," Pochettino told Telefoot. "We've been trying since our first day to set up different concepts. 

"I'm happy with their efforts, their attitude. It's only the beginning. They have to adapt to us [the staff] and we have to adapt to them. There is work to be done to get to know each other better.

"We have to improve in several situations, especially with the ball, but it was difficult because the preparation has was very short.

"I am disappointed, because we are PSG and we want to win. But we didn't have a lot of time to prepare for the match.

"We still have a lot of things to improve, to develop. This is not the result that we wanted."

As Manchester City's players huddled around the centre circle in number eight shirts to pay a poignant pre-match tribute to Colin Bell, it occurred a Pep Guardiola team might never have been so fittingly dressed.

England international Bell, widely revered as the finest player in City's history, passed away after a short illness on the eve Wednesday's 2-0 Manchester derby win the semi-final of the EFL Cup.

Bell, according to the loud and often repeated refrain of the Kippax Stand at City's old Maine Road home, was the greatest inside forward that the world had ever seen.

A technically gifted all-round midfielder, somehow simultaneously graceful and powerful, Bell thrived in those dangerous pockets between winger and centre-forward to cause maximum damage in Joe Mercer and Malcolm Allison's celebrated City teams of the late 1960s and early 1970s.

The inside forward had long gone out of fashion before Pep Guardiola ushered in his era of "free eights". From Xavi and Iniesta, through Thiago Alcantara and Toni Kroos to David Silva and Kevin De Bruyne, City's former Barcelona and Bayern Munich boss delights in filling his side with such players.

During Sunday's swaggering 3-1 win over Chelsea, De Bruyne was joined in the line-up by Phil Foden, Ilkay Gundogan and Bernardo Silva. That quartet of playmakers probably would have resumed duties together at Old Trafford had Silva not been suspended.

After paying tribute to City's eternal eight, Guardiola's team of number eights got to work. Where the league fixture on this ground a month ago was as stodgy as the pitches Bell graced in his heyday, the pop and fizz to the early passing was much more in "Nijinsky's" image.

Copious injuries, late positive COVID-19 tests and a suspension; a highly anticipated clash between Serie A leaders Milan and defending champions Juventus at San Siro on Wednesday threatened to seriously underwhelm.

There was no Alvaro Morata for the Juve, while full-backs Alex Sandro and Juan Cuadrado were forced to sit out after returning positive coronavirus results.

Milan were without star striker Zlatan Ibrahimovic and their midfield was decimated by the absences of Sandro Tonali (suspension), Ismael Bennacer (injury) and Rade Krunic (coronavirus). The dire situation forced Stefano Pioli to start right-back Davide Calabria alongside Franck Kessie in the central pivot.

Yet despite the difficulties faced by both teams, a thriller was served up in Milan, and Federico Chiesa took centre stage as Milan's unbeaten streak in Serie A was ended at 27 by a 3-1 loss to Juve.

ACT ONE

The last time Milan held a superior position to Juve heading into a meeting of the sides was in November 2015, and on that occasion the Bianconeri emerged triumphant thanks to a goal from Paulo Dybala.

While the Argentina international, who has been struggling for consistency and dealing with a fever, was not the man to open the scoring on this occasion, he still played a pivotal role.

After drifting across the pitch to offer support to Chiesa, he held up a pass from the winger before returning it by dragging the ball back behind his standing leg and flicking it around Alessio Romagnoli.

It was weighted perfectly for Chiesa's dart into the box, which was not tracked adequately by Theo Hernandez, and he drilled a shot across Gianluigi Donnarumma into the bottom-left corner.

ACT TWO

A thoroughly entertaining first half saw Juve control possession but Milan get more shots away. There were 21 in total during the opening 45 minutes, 12 for the Rossoneri and nine for Juve, a number only two Serie A games this season have exceeded (Sassuolo v Cagliari – 22, Cagliari v Napoli – 23).

Wojciech Szczesny kept out Samu Castillejo, Rafael Leao and Hakan Calhanoglu, as well as stopping Aaron Ramsey from scoring what would have been an incredible own goal, before he was finally beaten by the unlikely source of Calabria.

Juve did not appear happy the goal was allowed to stand, with Calhanoglu putting in a contentious challenge on Adrien Rabiot to launch the counter-attack from which Leao fed Calabria to guide a fine finish into the top-right corner.

It ensured Milan found the back of the net for a 36th consecutive Serie A game – a run only bettered by Juve (43 in 2014 and 44 in 2017) – with Leao involved in an eighth goal in 12 league appearances this season, one more than he managed across the entirety of the previous campaign.

ACT THREE

Unsurprisingly the game was far less open after the interval, but Chiesa was able to separate the teams once more.

Again it was Dybala leading the supporting cast, spotting his team-mate in space on the right and drilling a pass across for him to attack Hernandez once more.

Just as in the first half, Chiesa's feet proved too quick as he shifted the ball to his left and threaded a curling shot between Hernandez and Romagnoli and into the bottom-left corner. It was his sixth goal involvement (three scored, three assisted) against Milan in Serie A, which is more than he has managed against any other side.

The 23-year-old is proving himself to be a man for the big occasion. Since the start of last season, he has been thoroughly impressive against the best teams in the league. In that time, he has had a hand in three goals against Milan (two scored, one assisted) and Atalanta (two scored, one assisted) and also scored in meetings with Inter, Napoli and Lazio.

THE UNDERSTUDIES

While Cristiano Ronaldo was arguably the quietest of Juve's forward-thinking players, Chiesa made way for Dejan Kulusevski a minute after his goal, as Weston McKennie entered for Dybala.

The pair combined to put the game to bed in the 76th minute, McKennie sweeping in after a fine run down the right from Kulusevski.

The sole consolation for the Rossoneri was that they remained top of the league due to Inter's defeat to Sampdoria earlier on Tuesday, but Chiesa's blockbuster display proved Juve will not be content with solely being extras in the title race this season.

Lionel Messi scored twice as Barcelona ruined Marcelino's first match in charge of Athletic Bilbao with a hard-fought 3-2 triumph at San Mames.

Inaki Williams made an instant impression on Athletic's new boss - appointed following the dismissal of Gaizka Garitano - by scoring inside three minutes for the home team on Wednesday.

Capitalising on a ridiculously high defensive line, the forward ran clear from inside his own half and, after cutting back inside a half-hearted challenge from Clement Lenglet, fired low past Marc-Andre ter Stegen to break the deadlock. 

However, with Messi leading the way, Barca recovered from the setback to turn the game around by the interval, albeit with some help from the hosts.

Unai Simon was tempted out to deal with Messi's seemingly over-hit cross for the equaliser, the alert Frenkie de Jong stretching out to volley the ball back into the middle for Pedri to nod into an unguarded net. 

The Athletic goalkeeper was caught again when his side conceded seven minutes before the break, Pedri the provider as his clever back-heeled assist set up the supporting Messi to pass the ball in, Simon - who had initially rushed out expecting the teenager to shoot - stranded out of position.

Athletic briefly threatened a recovery of their own early in the second half, yet it was always their opponents who carried the far greater threat in attack.

Having seen a goal ruled out for offside and a long-range shot denied by a post, Messi finally scored again when sweeping Antoine Griezmann's square pass home via the underside of the crossbar.

There was late drama when a turnover in possession allowed Alex Berenguer to tee up Iker Muniain for a first-time finish that cut the gap in the 90th minute, but Barca held firm to claim all three points.

Paris Saint-Germain failed to get off to a winning start under Mauricio Pochettino as they were held to a 1-1 draw by Saint-Etienne in Ligue 1.

Thomas Tuchel oversaw a 4-0 defeat of Strasbourg in PSG's final game of 2020, although it was not enough for the German to keep his job as the defending champions sat third.

And Pochettino was unable to mastermind a victory to kickstart his reign as a rather lethargic PSG struggled to build on Moise Kean's 22nd-minute equaliser.

That goal cancelled out Romain Hamouma's opener, but PSG were ultimately fortunate Saint-Etienne did not snatch a first win over the capital club since 2012, their point enough to move second but three points behind Lyon.

Both goalkeepers were called into action inside the opening 10 minutes as Keylor Navas denied Harold Moukoudi at one end before Moise Kean tested Jessy Moulin at the other.

Yet Pochettino's tenure had its first setback 19 minutes in when PSG played themselves into trouble, Idrissa Gueye's slip pounced on by Denis Bouanga, with Hamouma supplying a neat finish over Navas.

PSG hit back inside three minutes, however, as Marco Verratti played in Kean to slam in the first goal of the Pochettino era on the turn.

Mathieu Debuchy's low strike forced Navas into a smart stop before half-time, and PSG's goalkeeper came to their rescue again in the second period, blocking Bouanga's path to goal.

Navas was beaten with 20 minutes remaining, but the crossbar kept out Bouanga's header.

Kean snatched at a good chance as PSG sparked back into life, yet Angel Di Maria's low strike – well saved by Moulin – was the only shot on target the visitors managed in the second half as Pochettino was forced to settle for a point.

Federico Chiesa scored a brilliant brace as Juventus ended Milan's unbeaten start to the season and clinched a crucial 3-1 victory that moves the Serie A champions up to fourth in the table.

Andrea Pirlo's men produced a scintillating attacking display to become the first team to beat leaders Milan in the league in 28 matches and did so without leading scorer Alvaro Morata.

Ably assisted by Paulo Dybala on both occasions, Chiesa scored with confident finishes in either half and Milan's waves of attacking pressure found Juventus goalkeeper Wojciech Szczesny in fine form before Davide Calabria found the net.

The Bianconeri, who added a third through substitute Weston McKennie, will hope this was a turning point in a tumultuous season, having played with the guile and poise they have lacked for so much of it, while Milan will reflect on a missed opportunity to extend their lead at the top to four points after Inter lost to Sampdoria.

Juventus' high press overwhelmed Milan early on and Paulo Dybala tested Gianluigi Donnarumma from six yards before Chiesa crashed a thunderous shot onto the post.

With 18 minutes played the Old Lady's superb start paid dividends, Dybala's smart back-heel sending Chiesa into the area and the Fiorentina loanee sent a low shot bouncing into the far corner of Donnarumma's net from 12 yards.

Juve had Szczesny to thank for keeping them ahead with a string of saves but he was powerless to stop Calabria's shot from finding the top corner after the lively Rafael Leao teed him up – although Juventus claimed Adrien Rabiot was fouled in the build-up.

Szczesny got down well to save Diogo Dalot's powerful 20-yard shot as Milan came out firing after the interval but Juve weathered the storm before Aaron Ramsey missed a golden chance to give them the lead, shooting wide from close range with just Donnarumma to beat.

Just after the hour mark, Chiesa struck again, Dybala picking him out on the edge of the box where he bent a superb left-footed shot into the far corner.

Chiesa then left the field with an injury and was replaced by McKennie, who swept home Juventus' third in the 76th minute after a jinking run through Milan's defence by fellow substitute Dejan Kulusevski.

What does it mean? The fightback is on

Juventus have now won three of their last four Serie A matches and are playing with real verve.

Having had such a short pre-season with his side, Pirlo has been playing catch-up but his expansive, fast-attacking style of play seems to be finally bearing fruit as his players cut out defensive errors.

Dybala at his best

Dybala's two assists were as incisive and spectacular as Chiesa's finishes and the Argentina international also won six duels to help Juventus stay on top.

Leao rues missed chances

Milan could have been ahead at half-time had Leao made more of the clear-cut chances that fell to him and, despite his assist for Calabria's goal, he will remember this game for his three unsuccessful shots at goal.

Key Opta Facts

- Juventus have won 14 of their last 16 Serie A games against AC Milan (L2).
- AC Milan are enjoying the third-longest streak of Serie A consecutive matches with a goal: 36. In the history of the competition, the only two longer streaks have both been by Juventus: 43 in 2014 and 44 in 2017.
- Federico Chiesa has been involved in six Serie A goals against AC Milan (3 goals, 3 assists).
- Prior to Wednesday, the last time a player twice assisted the same Juve team-mate was in February 2018 against Sassuolo (Federico Bernardeschi to Gonzalo Higuain).

What's next?

Milan are at home against struggling Torino on Saturday, and Juventus entertain in-form Sassuolo a day later.

John Stones ended his long goal drought as holders Manchester City secured a 2-0 derby win over Manchester United to set up an EFL Cup final showdown with Tottenham.

Stones has been outstanding at the heart of the City defence since forcing his way back into the side this season and he scored his first City goal in 1,162 days at Old Trafford on Wednesday.

The in-form centre-back had earlier put the ball in his own net early on but Marcus Rashford was offside, summing up how his fortunes have changed.

United were unable to respond following Stones' goal early in the second half and Fernandinho doubled City's lead seven minutes from time with an excellent finish.

Pep Guardiola's side were worthy winners, dumping their neighbours out at the same stage they did 12 months ago as they aim to win the competition for a fourth consecutive season.

Diego Simeone hinted at the idea he could leave Atletico Madrid at the end of the season after their awful Copa del Rey defeat to third-tier Cornella.

Simeone's LaLiga leaders exited the Copa on Wednesday, losing 1-0 to a goal from former Atletico B defender Adrian Jimenez.

Ricard Sanchez was sent off as Atleti slumped to a shock reverse swiftly described by the Spanish media as a "disaster" among the very worst of Simeone's 502 games in charge of the club.

The long-time coach named a strong side, including record signing Joao Felix, but saw his team remarkably unable to register a single shot on target.

Copa failings are a familiar story by now, though, with the Rojiblancos losing to Cultural Leonesa last season. Meanwhile, they have not beaten a fellow LaLiga outfit in the competition since seeing off Elche in January 2017.

Simeone recognised Atleti are struggling in one-off knockout matches - also losing in last season's Champions League to RB Leipzig - but added the surprising qualifier that it would be an issue to consider only if he was still at the helm next year.

"[Cornella] played better," he said. "In the whole game, what they wanted was always done better than what we wanted.

"They took advantage of the set-piece situations and immediately found the goal.

"The boys tried to compete in the best way. In the first half, we had more chances, and in the second, it was rockier. It got difficult after the red card.

"This competition has not given us satisfaction in recent years but solutions will have to be found if we are here next year."

Saul Niguez, captain on the night, identified the same problem as he added: "We apologise to the fans. We never throw away competitions, but in these single-game editions we are not doing well."

Given Atleti's struggles, the decision to replace Joao Felix with 18-year-old debutant Mario Soriano 15 minutes from time prompted some discussion.

But the Portugal international mustered only one shot, which was blocked, prior to his withdrawal and failed to create a single chance - unlike his replacement.

Joao Felix epitomised the visitors' display as he completed just 13 of his 21 attempted passes and lost possession 13 times, winning none of his three aerial duels.

The change still appeared a big call, yet Simeone explained his star forward was struggling with an ankle injury.

"He was hurt," Simeone said. "We looked for a fresher guy. He had a bruised ankle and we wanted to find a guy in good condition."

Atletico Madrid were the victims of a Copa del Rey giant-killing for a second successive season as Diego Simeone's side went down 1-0 to Cornella.

LaLiga leaders Atleti lost 2-1 to Cultural Leonesa in the round of 32 last season, and slumped out to Segunda B opposition on Wednesday.

The 10-time Copa winners fell behind to Adrian Jimenez's sensational flick seven minutes into the second-round tie in Catalonia.

Saul Niguez hit the woodwork and Lucas Torreira went close with a free-kick, but Ricard Sanchez's second booking compounded Atleti's issues as minnows Cornella claimed a famous triumph.

Sanchez was fortunate not to concede a penalty for handball in the opening minutes, before Jose Gimenez, making his 200th Atleti appearance, scythed down Raul Prieto.

With Gimenez, who was booked for his troubles, off the pitch receiving treatment, Cornella added insult to injury, with Agus Medina's cross flicked home expertly by Jimenez.

Atleti seemed set to restore parity shortly after the 20-minute mark, yet Angel Correa saw two efforts blocked either side of Saul hitting the crossbar.

Though Atleti were seeing over 60 per cent possession, they would have been 2-0 down heading into the break if not for Miguel San Roman's save from Pablo Fernandez.

Vitolo got in behind Cornella's backline early in the second half, only for an errant offside flag to deny him a chance to equalise.

Torreira's curling free-kick was inches away from levelling proceedings, though Atleti were then fortunate that Eloy Gila flicked over from close range at the other end.

Sanchez's frustrating night was made worse when he was deemed to have kicked out at Cornella goalkeeper Ramon Juan – the full-back seeing red just 11 minutes after receiving his first booking as Atleti's comeback efforts proved futile. 

Antonio Conte felt Inter were hard done by as their Scudetto ambitions suffered a blow with a 2-1 defeat at Sampdoria. 

Alexis Sanchez missed a first-half penalty before Antonio Candreva converted from the spot for the hosts at the Stadio Luigi Ferraris. 

Keita Balde doubled Sampdoria's advantage in the 38th minute and, although Stefan de Vrij reduced the deficit and Romelu Lukaku - short of match fitness - came off the bench, Inter were unable to pull level. 

Milan host champions Juventus in a mouth-watering San Siro clash later on Wednesday, where victory would increase the Rossoneri's advantage over Inter at the summit to four points. 

The result halted an 11-match unbeaten run for Conte's men and he refused to be too harsh on his players after they failed to overcome a chastening first half. 

"We found ourselves going from the missed penalty to having a penalty against us. There was this one-two from Sampdoria that clearly created some difficulties for us," he told reporters. 

"At the same time, the team was doing well, in the first few minutes they created a lot of scoring situations. Sometimes you lose games you deserve to lose, other times there are situations where you can score and you don't." 

Despite those missed chances and struggles in attack for Lautaro Martinez, Conte refused to blame Lukaku's recuperation from a thigh strain for Inter falling short.

"It wasn't the first time we played without Romelu, we know that he is a player with certain qualities, but he wasn't 100 per cent and you saw it when he came on," he said. 

"Sorry because I think we deserved something more." 

Christian Eriksen was also introduced from the bench, despite being told he can leave Inter this month. 

"I always try to exploit the players according to the situations that arise and I am at the club's complete disposal on every decision," Conte explained. 

"I get to work, as I have always done since I have been at Inter, but every decision will always be shared." 

Inter return to action with a crunch clash against third-placed Roma on Sunday.

Pele has denied changing his Instagram bio after Cristiano Ronaldo overtook his haul of 757 goals in official competitions.

Five-time Ballon d'Or winner Ronaldo moved on to 758 career goals with a double in Juventus' 4-1 victory over Udinese on Saturday.

It came just two weeks after Brazil great Pele, a three-time World Cup winner, saw his record for the most goals with a single club - 643 at Santos - surpassed by Barcelona captain Lionel Messi.

Following Ronaldo's goals against Udinese, Pele was accused of updating his Instagram bio to include "Leading Goal Scorer of All Time (1,283)", a total that remains the subject of much debate.

However, the 80-year-old has refuted the allegation, insisting he is not trying to detract from the achievements of Ronaldo and Messi.

"I was accused by the press of having changed my Instagram bio to overshadow these big stars that are breaking my records," Pele posted on Twitter.

"The bio text has always been the same since I joined the platform. None of this should distract us from their incredible achievements."

Only Czech striker Josef Bican, who is credited with scoring 805 goals, lies ahead of Ronaldo in the all-time goalscoring list.

After Messi scored his 644th goal for Barcelona, Santos published an article on their official website – attributed to club historian Fernando Ribeiro – with the headline, 'King Pele – 1,091 goals for Santos FC'.

Ribeiro claimed that Pele's official haul for Santos was 1,091 when friendlies against some of the world's best teams, including Barca and Inter, were included.

Veronika Kudermetova started the new season in style by beating 10th seed Anett Kontaveit in the first round of the Abu Dhabi Women's Tennis Open on Wednesday.

Kudermetova had won her only two previous singles matches against Kontaveit and maintained that perfect record with a 7-5 6-1 victory.

The world number 46 from Russia broke four times to seal her place in the second round, with Kontaveit winning just 48.4 per cent of points on her first serve in a rusty beginning to the 2021 campaign.

Donna Vekic was another seed to fall at the first hurdle as Bernarda Pera consigned the Croatian to a 7-6 (12-10) 2-6 6-4 defeat at Zayed Sports City International Tennis Centre.

Kirsten Flipkens could face top seed Sofia Kenin in the second round after defeating Laura Siegemund 5-7 7-5 6-4.

Ons Jabeur is aiming to break into the top 10 this year and the 15th seed got up and running for the season by seeing off Anastasia Pavlyuchenkova 7-6 (7-3) 6-3.

Daria Kasatkina, Yulia Putintseva and Ajla Tomljanovic were among the other players who advanced to round two.
