In the 37th round of the Premier League, Manchester United played Arsenal at home. Onana and Casemiro made back-to-back mistakes to give Trossard an easy lead for Arsenal.
In the game against Crystal Palace, Casemiro made two mistakes that led to two goals for Crystal Palace. Not only that, Casemiro was broken by his opponent 8 times in this campaign, setting a record for a single Premier League game this season. Casemiro also became the first Manchester United player in eight years to break through seven times in a single game.
However, with no one available at the back, Ten Hag had no choice but to continue with Casemiro at centre-back. It was Casemiro's fourth consecutive game at centre-back, having made 504 appearances before this season but only five at centre-back. Considering the fluid running of Arsenal's attacking line, Casemiro will face an even bigger test.
It is worth highlighting that Casemiro and Evans are United's 14th centre-back partnership this season, while Saliba and Gabriel have started together for the 33rd time in 37 Premier League games. However, Bruno Fernandes continued to be absent and Ten Hag started Amurabat with the aim of strengthening the interception in the middle.
However, in the 20th minute, Kai Havertz burst into the box and crossed for Leandro Trossard to slotte home from a tight angle.
Arsenal was able to score first, which was directly related to Onana and Casemiro's mistakes. First, Onana made a big mistake and passed the ball directly to the opponent, and then Casemiro made an offside error, allowing Havertz to break the offside trap and then cross, at this time Casemiro looked at the ball and did not look at people, allowing Trossard to get a chance to push.
It is worth mentioning that it was the 82nd goal United conceded this season, equalling the record conceded in 1970-71.
The slump in form at Manchester United also led to Casemiro's failure to make the Copa America squad, which was a heavy blow to the 32-year-old.
