James and Wan-Bissaka have been training with their new team-mates over the past week.
Manchester United midfielder Juan Mata has heaped praise on new signings Daniel James and Aaron Wan-Bissaka and is hoping the duo bring a lot to Ole Gunna Solskjaer's side.
Mata also revealed both players, aged 21, are settling well into the United team as they prepare to prove their worth.
"You can see it from the first moment - they both have their qualities," he said in an interview on United's official app. "Wan-Bissaka has played in the Premier League before and James has been doing great things at Swansea.
"Hopefully they can give us a lot. They are very important because they are very young and very hungry to give their best for the club."
Mata, who signed a new two-year deal with the Red Devils in June, continued: "It is true that time flies and it feels like yesterday when I was 22, 23, but I have been playing football now for a long time - 12, 13 years as a professional.
"I enjoy that part of the game, speaking to young players now and trying to tell them how I understand football, how I think professional football players should be, but obviously my focus is still on giving my best on the pitch.
"I want to play as much as I can, I want to score and to assist. That is my main focus. But I enjoy speaking with Marcus [Rashford], with Mason, with Jimmy, with Gomes and Chongy. They are great guys and they have a great future ahead."
