The summer signing from Liverpool had played five times for his new club at the Fifa Club World Cup, where they reached the semi-finals, under new boss Xabi Alonso. But this was his Bernabeu bow and he received a standing ovation when he was replaced by Dani Carvajal in the 68th minute. Kylian Mbappe scored the only goal from the penalty spot as Real won their opening league game of the season in Alonso's first domestic match in charge. The France international sent goalkeeper Sergio Herrera the wrong way after he had been fouled in the box. Madrid, who finished second last season under Carlo Ancelotti, were dominant and could have scored more. Defenders Dean Huijsen - also making his La Liga bow after a summer move from Bournemouth - and Eder Militao forced saves from Sergio Herrera from long range. There were also debuts for £43m former Benfica left-back Alvaro Carreras and teenage midfielder Franco Mastantuono, a £38.5m recruit from River Plate. Osasuna had Abel Bretones sent off in injury time for catching Goncalo Garcia.

Mikel Arteta accepted his side were not at their best and it is only the first game of the campaign, with new players settling in - but the ability to get a result even when not playing well could be a big thing for the Gunners as they look to win a trophy this season. Manchester United pinned Arsenal back for large parts of the match, had 61% possession and 22 shots as they looked to get back level - but the visitors managed to keep them at bay. Arsenal looked uncharacteristically open at times in the first half, with Arteta extremely animated in his technical area.

The midfielder, 27, was a doubt for selection amid ongoing talks with Tottenham, but started for the visitors at Stamford Bridge and powered home a free-kick from 20 yards in the 13th minute. However, the strike was ruled out by referee Darren England after a VAR check because Palace defender Marc Guehi - also linked with a move away to Liverpool - was within one metre of Chelsea's wall when the free-kick was taken. The rule, which has been in place since 2019, is rarely applied but cost Palace, who missed further chances through striker Jean-Philippe Mateta and Maxence Lacroix, and were the better team earlier on. Chelsea celebrated becoming world champions over the summer before kick-off but delivered a flat first-half display. Their best chances fell to substitute debutants Estevao Willian, Liam Delap and Andrey Santos after the break. It was just 35 days since Chelsea won the Club World Cup final against Paris St-Germain in New Jersey, which shortened their pre-season preparation to just 13 days. Five players made league debuts for the Blues on Sunday - Estevao, Delap, Santos, Joao Pedro and Jamie Gittens - after another busy summer of business at Stamford Bridge. By contrast, Palace started their own pre-season a day before Chelsea's 2024-25 campaign had even finished. The final two weeks of the window could be crucial for the Eagles with two of their star players potentially leaving the club.

Diaz celebrated a winning start to his career in Germany, having joined Vincent Kompany's side from Liverpool this summer for £65.5m on a four-year deal. The Colombia winger headed home from Serge Gnabry's cross in the 77th minute to double Bayern's lead. England captain Kane had broken the deadlock in the first half, taking advantage of a poor clearance to slide the ball into the bottom corner. Jamie Leweling pulled a goal back for German Cup winners Stuttgart in the 93rd minute, but it proved to be a consolation as Bayern earned their first piece of silverware of the season. After his goal, Diaz paid tribute to his former Liverpool team-mate Diogo Jota - who was killed in a car crash in July along with his brother Andre Silva - by replicating one of the Portugal forward's celebrations. Bayern have now won the season curtain-raiser a record 11 times, while Kane has added a second piece of silverware in Germany after winning his first career trophy last season. Bayern, who missed out on the title in 2024 for the first time in 11 years but triumphed under Kompany last season, will begin their title defence against RB Leipzig on 22 August.

Raphinha nodded in the opener following a fine right-wing cross from Lamine Yamal. Ferran Torres smashed in their second goal, while Mallorca captain Antonio Raillo was lying on the ground in the box with a head injury after blocking a Yamal shot. Manu Morlanes, who was booked for dissent in the aftermath of that incident, was shown a second yellow card soon after for a foul on Yamal. And Vedat Muriqi was sent off for a high boot on debutant Barcelona goalkeeper Joan Garcia, a decision upgraded from a yellow card after a video assistant referee (VAR) review. It took Barcelona 60 minutes including stoppage time to score past the nine men, Yamal hammering in their third goal with almost the last kick. Rashford came on in the 69th minute for his Barcelona debut, becoming the first English player to feature for the first team in a competitive game since Gary Lineker in 1989. The 27-year-old, on a season-long loan from Manchester United, played as a centre-forward but did not have any chances to score. Rashford and fellow summer recruit Garcia had only been registered with La Liga on the morning of the game because of Barcelona's financial issues.
