"He's got to show courage" - Chris Wilder says David Luiz should have seen red for early challenge in Sheffield United's defeat to Arsenal

Luiz got himself into trouble when he was closed down by Oli Burke, with the ball rebounding towards Arsenal's goal.

Luiz tugged on Burke's shirt to drag him back and Arsenal 'keeper Bernd Leno got to the ball first. Referee Lee Mason took no action, a few weeks after United's John Egan saw red at Aston Villa for grappling with Ollie Watkins as the two players battled for a ball bouncing towards goal.

And Wilder, invited to compare the two incidents in his post-match press conference, revealed: "It makes no odds what happened to John Egan because that was a mistake.

"Mike Riley admitted that to me, and the Berge one last week was a mistake too. There was another one today.

"The referee has got to show courage. There are five officials now, I see it and all our staff and subs see it and five people don't.

"He's pulled his shirt. I'm not clutching at straws or grasping, Oli's shirt has clearly moved.

"All the stuff with VAR was supposed to be about making the right decision, is it the right decision? He pulls his shirt when going through and the decision has got to be made.

"With John Egan, the decision was made there. He didn't go over to look at the screen, and I don't understand why. I'm going to be annoyed and frustrated.

"We're looking for small margins that might help us. I think Luiz should get sent off and I think it's clearer than John's at Villa. When it's not going your way, you look for something to go your way."

United went on to lose the game 2-1, with Arsenal scoring two quickfire goals through Bukayo Saka and substitute Nicolas Pepe. David McGoldrick pulled one back late on, with United's first Premier League goal of the season so far, but the Blades could not complete a comeback that Wilder admitted would have been "smash and grab".
