Manchester United beat Chelsea in the last round, and Casemiro was sent off in the first half, and Rooney criticized Casemiro in an interview.
Speaking of Casemiro's performance, Rooney said: "For an experienced player, it's too stupid and childish. United have completely controlled the game. If you look at the first foul, you will understand that he doesn't have to tackle with Chelsea playing one less. Yes, the field is slippery, but that yellow card is too stupid.
I thought Amorin would replace him because you were always worried that this would happen, and he actually got the second yellow card. It's a bit harsh because he played the ball, but you can see him pulling Andre Santos down. You wouldn't have thought that an experienced player would do something like this, which could lead to Manchester United losing.
I think this is the only way he knows to play. He is passionate and likes to steal and finish the steal, but I think he could have been calmer today."
