Paul Pogba starts on the bench for the Manchester United-PSG match on Tuesday, with no place for new signing Donny van de Beek in the starting lineup.
United manager Ole Gunnar Solskjaer has opted for a back three of Axel Tuanzebe, Victor Lindelof and Luke Shaw.
The full-backs are Aaron Wan-Bissaka and new signing Alex Telles.
United's midfield consists of Fred and Scott McTominay, behind Bruno Fernandes, Marcus Rashford and Anthony Martial.
Manchester United team to face PSG: De Gea, Telles, Shaw, Lindelof, Tuanzebe, Wan-Bissaka, Fred, McTominay, Fernandes, Rashford, Martial.
"We hope the players won't be away for too long," the manager said on Monday night, "Edinson needs a few more days training before we can think about the weekend.
"Hopefully the same with Harry, Eric, and Mason as well, but we're not sure about that."
Asked about Greenwood's issue, Solskjaer replied, "It's just a niggle. As young as he is, we don't want to take any chances with him. Hopefully by the weekend, he'll be fine again."
Fernandes only found out about his appointment as captain while sat next to his manager at their pre-match press conference in Paris.
Asked about the role, the €75million man said, "I was not expecting this, I have found out the same time as you!
"For me, it's an honour. I will be captain for my teammates and to be captain of Manchester United is an important achievement for me.
"But I think everyone is the captain. Everyone needs to help and be a leader in their own way, leadership is different in every player. Tomorrow will not be about me but the team.
"Leading is every day in the training ground, every game and everyone is doing their job to lead the team in the way they think is best."
