Roy Keane has now predicted who will win on Sunday... Arsenal or Man Utd

Arsenal face Manchester United on Sunday in what could end up being a season-defining game for both sides.

A win for Arsenal would allow the Gunners to keep the pressure on in the title race, while a loss for Manchester United would likely mean that the Red Devils won't be playing European football next season for the first time in a long time.

Both sides will be desperate to win this one, but with Arsenal sitting top of the table and United struggling in eighth, it's not hard to fancy the Gunners heading into this one.

Speaking in Stick to Football, Roy Keane has made his prediction for this weekend's game.

Roy Keane predicts Man Utd vs Arsenal

While other pundits argued over the result of this game and give long-winded explanations, Keane got straight to the point.

The former United captain doesn't have high hopes for his former club heading into this weekend, bluntly stating that he thinks Arsenal will win this one 2-1.

"2-1 Arsenal," Keane said.

Arsenal could embarrass Manchester United

Keane is being rather conservative with his prediction here.

Manchester United are about as bad as they ever have been. Their players look utterly defeated, the tactics aren't working and there is an injury crisis ongoing.

After losing 4-0 to Crystal Palace on Monday, United could be in line for another embarrassing defeat against Arsenal this weekend.

That being said, you can never fully discount the Red Devils when they're playing at Old Trafford, and while Arsenal could end up hammering United here, it also wouldn't be that much of a shock if United did manage to nick a result.

This is undoubtedly one of the most important games of the season, and while Arsenal will be desperate to win to keep their title hopes burning, United will certainly be keen to spoil the party.
