Luke Shaw is expected to miss the rest of Manchester United’s season and England’s World Cup qualifier against Scotland after suffering another injury setback.

Shaw will discover the results of a scan on a foot injury in the next 24 hours but is reluctantly preparing to write off his season, in another blow for the 21-year-old defender.

The left-back was taken off after eight minutes of United’s 1-1 draw with Swansea on Sunday, with manager Jose Mourinho claiming the problem “must be a big injury” in a swipe that appeared again to question his commitment.

Shaw required medical treatment on the pitch after the incident and United sources believe he could be ruled out for at least four weeks, following a scan on Monday.

Mourinho is already battling a severe injury crisis at the back, with Phil Jones and Chris Smalling unavailable while Eric Bailly also came off in the second half at Old Trafford.
