The Red Devils navigated a second leg in the Europa League against Real Sociedad, drawing 0-0 to go through to the last 16 4-0 on aggregate.
"Of course, that's why he played there [to provide another option amid an injury crisis] ," Solskjaer told reporters when asked why defender Axel Tuanzebe played in central midfield in the second half against Sociedad.
"It's one of those positions now we suddenly have Scott, Donny and Paul [Pogba] out. We've been really well off before and now we might have to look at options because I'm not sure if any will be available.
"Scott, Donny and Edinson we hope that they can be available for the weekend, but I'm not sure. Paul is still out for a few weeks unfortunately."
