What is certain is that Casemiro will not be in a good mood these two weeks.
He was humiliated in Manchester United's 4-0 defeat to Crystal Palace and was not included in Brazil's squad for the Copa America. He was again the main responsible for United's narrow 1-0 defeat to Arsenal yesterday.
A recent cameo at centre-back has become United's frustrating poster man at the end of the season. His repeated mistakes and resulting failures have only deepened doubts about Ten Hag's future at Old Trafford.
Casemiro won the Champions League with Real Madrid two years ago, but his form is now on a dip and his form will raise questions about his future in the Premier League, even given United's injury problems. Carragher said this week: "It's time for him to retire. Carragher seems to have forgotten that Casemiro has two years left on his high-paying contract with Manchester United.
Below, we take a look at Casemiro's performances over the past week.
The first goal conceded against Crystal Palace
A night that makes Casemiro shiver forever. He was ridiculed and sympathized.
The game started with a puzzling mistake. Olise played the ball normally, but Casemiro panicked and fell to his feet 40 yards from his own goal, but there was no chance of stealing the ball at all.
The defence failed and Olise raced out of the box, shook off Mainou and into the United penalty area, firing low enough to beat Onana.
Casemiro, the former midfielder, could only stand from a distance and watch the team concede the goal.
Ashley Young told Sky Sports: "It's terrible. I don't know what he's thinking or doing. Maybe he thought Olis was going to retreat, but Olise saw that he was going to grab it, and then directly passed him, it was too easy. ”
The second goal conceded against Crystal Palace
It has something to do with Casemiro. The two teams battled in midfield, with Casemiro coming up and getting ahead of his team-mates in an attempt to win the ball for his team.
As a result, good intentions do bad things. Casemiro couldn't get his hands on the ball and Chris Richards played straight to Mateta, who immediately dribbled straight into the space left by Casemiro.
Evans has also been involved in the defense, but the main responsibility is still on Casemiro.
He wanted to make up for his mistakes, but no matter how much he chased him, he couldn't catch up with his opponent. Carragher said: "It's really sad to see a great player perform like that. ”
The 4th goal conceded against Crystal Palace
When Mitchell scored the third goal for Crystal Palace, Casemiro was too slow to clear the ball in time. But the most embarrassing moment of his game came when his opponent scored his fourth goal.
Casemiro had stuck his position early and protected the ball, but then left a catastrophic picture.
Munoz took advantage of Casemiro's unpreparedness to unceremoniously knock him down and complete a steal and set up Olise to score with a cross.
When Munos passed the ball, Casemiro got up and couldn't get on his feet.
With three turnovers and three goals conceded, Casemiro really couldn't keep up.
Goal conceded against Arsenal
Another fatal mistake. You could say that he wanted to stay behind to protect Onana, but his walking behavior was absolutely unforgivable.
He's not committed at all, he's lazy, he's as slow as a tractor, which is the intensity of an exhibition game. There was a gap of 5.5 seconds between Onana clearing the ball and Ben White getting the ball and instigating a fast break, but Casemiro was at the bottom of the team, at least 10 yards from his nearest teammate.
Kai Havertz on the right was out of an offside position and dribbled down to cross for Trossard.
The man who dragged the last to protect was Aaron Wan-Bissaka, but Casemiro once again pushed United into a difficult situation.
Roy Keane said, "You don't have to sprint with all your might, but you have to run forward!" It's hard enough to play, the basics have to be done well, and he didn't do it well. In this case, the veteran player will definitely move forward, and the action must be faster, but he is slow, and there is no excuse for this. ”
Casemiro's career is about to come to an ignominious end.
