Manchester United boss Ole Gunnar Solskjaer says it was the right time to promote Shola Shoretire.
The 17 year-old midfielder was added to the first team squad last week.
Solskjaer said: "Of course. It's a decision we had to make - are they going to train with us and travel by themselves and not be a part of the U23s group and we felt with Shola it was time for him to train with us.
"In the Reserves games he's just got to travel by himself, he can't be in the dressing room, but we felt it was the right thing to do for him."
