Manchester United boss Erik ten Hag says there's no underestimating the importance of a fully fit Casemiro.
The midfielder is in line to start at Aston Villa today.
Ten Hag said: "He gives you calmness and composure on the ball
"He gives you options, he sees the critical pass, so he is always a step ahead of his opponent to break lines.
"So he is a very important player for our game and we're happy he's back."
