The two European heavyweights come head-to-head tonight at the Philip II Arena in Skopje.
Cristiano Ronaldo and Gareth Bale both took part in the session, despite being doubtful to start the match against the Red Devils.
Jose Mourinho last night admitted he’d be interested in signing Bale if he was available.
The Manchester United boss said: “If he (Bale) plays, it is the clearest signal that he is staying there.
“If he’s playing tomorrow I wouldn’t think of that [signing him].
“If he’s not in the club’s plans and what you are telling me is true (about Mbappe), that the arrival of another player would mean Gareth would be on his way out of Real Madrid then I would try to be waiting for him on the other side and be fighting with the other coaches who would like to have him on their team.
“But if he plays tomorrow it would be the best confirmation that he is wanted by the team.”
