Careless Casemiro costs Man Utd! Winners & losers after Brazilian's red card forces David de Gea & Co to battle for a point against Southampton at Old Trafford

A rash tackle by Casemiro meant the Red Devils' game-plan against a struggling Southampton went out the window, but an excellent defensive display meant they averted disaster.

De Gea made two spectacular saves to deny Theo Walcott but it is to the credit of his defence that he was not called upon more in a hugely entertaining, end-to-end game at Old Trafford.

Lisandro Martinez and Raphael Varane were brave and intelligent while full-backs Aaron Wan-Bissaka and Luke Shaw also worked hard to keep the energetic visitors at bay.

United could even have snatched a win, with Bruno Fernandes hitting the inside of the post in the second half.

The draw was obviously a disappointing result given the quality of the opposition but Liverpool's shock defeat at Bournemouth on Saturday means United are eight points ahead of the Merseysiders a week after their historic humiliation at Anfield. It could have been far worse.

Then again, if Casemiro had kept his head on they could have had a 10-point cushion in the top-four.
