Bastian Schweinsteiger is facing a race against time to be fit for Manchester United’s clash against Newcastle next Tuesday.

The Germany World Cup winner is also a doubt for United’s landmark trip to face Liverpool at Anfield five days later.

Schweinsteiger suffered a knee injury in the closing stages of United’s 1-0 FA Cup third-round win over Sheffield United on Saturday night after a 50-50 tackle with Chris Basham left him sprawled on the deck.

It initially appeared as if Schweinsteiger may have torn a ligament but, after a lengthy spell of treatment, the midfielder waved off the stretcher and finished the match, which was won by an injury-time penalty from Wayne Rooney.

However, Van Gaal is not convinced that the 31-year-old will be able to play any party in the Premier League clash at St James’ Park next week.

“I think it is a knee problem but we have to wait and see,” said the Dutchman at his post-match media conference on Saturday.

Schweinsteiger started alongside Marouane Fellaini in central midfield against the League One opponents.
