Manchester United boss Sir Alex Ferguson admits they've lost Jonny Evans for a fortnight due to injury.

Evans was United's only fit central defender heading into the game and failed to reappear for the second half as Dimitar Berbatov bagged a hat-trick.

Ferguson revealed: "Jonny came off injured. He has a calf injury and will be out for two weeks.

"We have had a nightmare the last few days. Phil Jones and Chris Smalling have both been ill. Rio Ferdinand called off yesterday with a back injury and Jonny Evans has come off at half-time.

"It does put you under pressure."
