Former Manchester United striker Dimitar Berbatov says West Ham will prove a huge test.

Berbatov has warned United about the dangers West Ham will pose.

He said, “Going to West Ham as a player, I never knew what I'd be up against. Sometimes they played like a team who could be anyone but, on other occasions, they were a team that would lose to anyone. It will be interesting to see which West Ham turn up on Sunday.

“The same could be said of United. A third consecutive 1-0 win would be a fantastic result for them but this will be a test. Paul Pogba is a doubt so, if he isn't fit, I'd start Matic in the midfield because he's a real team player and United will benefit from his experience away from home.

“United are on the up and I don't think they will lose this one. If forced to choose between the draw and an away win, I'd back United."
