Casemiro's nightmare week continued with Manchester United fans criticizing him for his part in Arsenal's first goal at Old Trafford.
the brazilian The horrendous campaign reached a new low after he was greatly at fault in Leandro Trossard's near post shot.
After passing the ball to United goalkeeper André Onana, who subsequently went long, Casemiro took too long to line up with his fellow defenders.
The Brazilian's slow run allowed Ben White to find Kai Havertz with a pass over the top where the German would otherwise have been offside.
By the time other Red Devils defenders arrived on the scene, Havertz had sent the ball to Trossard to score home.
Gary Neville told Sky Sports: “Casemiro has received some criticism in recent weeks and he is going to receive some more.
“He's going to get open, once Onana does, he has to get up. He has to be faster than that. Once he doesn't, he's in trouble.
“Trossard does what every good striker does.”
And he added: “That is a basic mistake by Casemiro… there are no excuses.”
And Man United fans agreed, with one fan writing on X, formerly known as Twitter: “Casemiro is costing us again.”
Another said: “Absolutely inexcusable of Casemiro… He literally gave up last month.”
A third joked: “Casemiro, with that kind of race you do along a road to warn a car, you realized that they are waiting for you.”
“Casemiro has to run. I don't know what he was doing. He doesn't even need to make a silly angle for the goalkeeper.
At half-time, Roy Keane said: “You don't need to run at 100%, but you do need to get on the pitch!
“This game is quite difficult, you have to do the basics well and he hasn't done that well at the moment.
“An experienced player takes the field.”
Casemiro was already a surprise starter again as an emergency centre-back following United's 4-0 defeat to Crystal Palace just six days earlier.
