Manchester United boss Erik ten Hag praised his players after their 0-0 draw with Southampton.
United earned the result after Casemiro was sent off in the first-half.
Ten Hag said, "Big compliments to the team. They showed big characer to play so long with 10. They were physically and mentally strong to get a point."
On whether Man Utd should have had a penalty: "Definitely. There's no doubt. I don't know why VAR didn't interrupt."
On the red card, the Dutchman also said: "Casemiro played over 500 games in Europe and never once got a red card. Now he has two in the Premier League.
"His absence is not the issue. We will deal with that. This game was influenced by the referee."
