The Englishman has continued his fantastic form under his new manager, grabbing a crucial goal against Watford on Saturday.
United ran out 2-1 winners and it was thanks to Rashford’s goal that they had a chance at all.
The striker’s effort came against the run of play as Solskjaer’s men struggled to get going all afternoon.
Marcus’ played all 90 minutes of the fixture so it’s a concern for many that he’s seemingly injured.
The academy product pulled out of the England senior squad during the recent international break due to his ankle and it appears he hasn’t completely recovered.
It could be that something happened during the Watford to aggravate the knock but it is worrying nonetheless.
Manchester United’s attack is completely different when Rashford plays and they can’t afford to lose him.
Had Ole known ahead of time the youngster was still carrying the knock the Norwegian might’ve not selected him.
Perhaps since Romelu Lukaku was also injured, Marcus was risked instead since he might’ve been considered the fitter of the two.
The Red Devils didn’t have any other senior options to rely on so hopefully the Belgian can pick up where his teammate left off.
