Manchester United have registered several of their youngsters for the Champions League - including new signing Rodrigo Possebon.
United have registered an additional three youngsters for the competition - striker Daniel Welbeck (17), defender Craig Cathcart (19) and midfielder Possebon (19).
Possebon, who was recruited from Brazil's Sport Club Internacional, made his debut for the reserves in midweek.
Former United star Paddy Crerand was impressed by the rookie's performance.
"I'm looking forward to seeing an awful lot more of this boy," Crerand told MUTV. "He was fantastic.
"He can use both feet, he's very calm on the ball and his passing is very, good. He's a big lad too, so he's strong and can hold off players.
"Players like Paul Scholes are always looking around and know exactly where they want to play the ball before it even comes to them.
"This kid looks as if he could be that kind of player."
