Manchester United defender Raphael Varane is still working his way back from a hamstring injury.

arane's recovery appears to be on track after the Manchester United star shared a photograph of himself working hard in the gym at Carrington on Tuesday.

United could potentially be without four players when they return to Premier League action against Watford on Saturday, which isn't good news for under-fire boss Ole Gunnar Solskjaer.

One of the key absences will be Varane, who is still expected to be a couple of weeks away from a comeback to action, says the Manchester Evening News.

The centre-back initially picked up a groin injury while on international duty for France last month that saw him miss three matches before returning in the 3-0 victory against Tottenham.

However, he lasted just 38 minutes of the following game away at Atalanta when he suffered a hamstring strain that ruled him out for at least a month.
