Manchester United goalkeeper David de Gea has reacted to Casemiro being sent off in the goalless draw against Southampton for a tackle on Charly Alcaraz.

De Gea told Sky Sports: “I think Casemiro was unlucky. He tried to touch the ball and his foot came up high. I think the referees need to show more consistency. Sometimnes they show a red card and sometimes they don’t.

“It’s going to be tough, he’s a big player. We will miss him for four games but we have a big suqad. We have players coming from the bench who do well. We will keep working hard.”
