Jamie Redknapp claimed Arsenal boss Mikel Arteta would have been "dancing around his living room" when Manchester United midfielder Casemiro picked up a yellow card that will now rule him out of Sunday's showdown.
The two teams meet at the Emirates this weekend in a clash that could have a huge impact on the title race, but United failed to make ground on the Gunners with their 1-1 draw at Crystal Palace on Wednesday evening. Bruno Fernandes fired the Red Devils in front, but a 91st minue Michael Olise free-kick broke United hearts.
It also robbed Erik ten Hag's side of the chance to leapfrog local rivals Manchester City into second and close the gap with table-toppers Arsenal. However, his main concern will be how he sets up against the Gunners without his main-man in midfield.
