The winger has missed the Reds' last two games - away to Newcastle United and at home to Liverpool - but did feature as a substitute in the preceding European game against AZ Alkmaar.
Speaking exclusively to MUTV before his pre-match press conference at Partizan Stadium, Solskjaer enthused:
“It's fantastic to have him back fit. He's been so lively and bubbly in training.
”I don't know how much game time we'll give him but he looks like he needs to catch up on lost time.
“It's been fantastic to see him with a big smile.
