Ole Gunnar Solskjaer was asked about the injuries picked up by Jesse Lingard and Anthony Martial during the 2-0 defeat to Paris Saint-Germain in the Champions League.
The talented duo were forced to sit out the second half of the first leg of the round-of-16 tie, with Alexis Sanchez and Juan Mata taking their place.
Lingard pulled up after sending the ball wide to Martial on the break towards the end of the first period, while the Frenchman sustained his problem earlier in the proceedings but soldiered on until the interval. Ole confirmed the issues are hamstring and groin for Lingard and Martial respectively.
With more big games on the horizon, starting with the Emirates FA Cup fifth-round clash at Chelsea next Monday and the next Premier League outing against Liverpool at Old Trafford on 24 February, there must be concern about the availability of two key members of Ole’s squad.
“You can’t give that [the injuries] as a reason [why we lost] because we have players like Mata and Sanchez to come on and they’re quality players,” Solskjaer told BT Sport.
“But, of course, Jesse and Anthony, they give us something. Let’s hope they’re not too serious.
”They’re muscle injuries, so we’ll just have to wait a couple of days.
“Jesse and Anthony are big parts of our squad and when they went out, in the second half we didn’t have enough movement,” Ole added at his press conference.
“We maybe need to find a different way of playing when Jesse and Anthony are unavailable.”
That could be the challenge for the caretaker boss if the pair are not available for the tough test at Stamford Bridge.
