"At United, the incredible winning mentality they have got is just unreal and you can learn so much from them. Speaking to people like Scholes, Giggs and [Rio] Ferdinand, all of them can give you something.
"Unfortunately, it's hard for a young player at United because there are so many great players, probably the best in the world. So you have to start at some point from somewhere and I'm very happy to be here. Hopefully, I can kick on and do well."
Wootton is in no doubt that his Reds team-mate can make a big impact at London Road.
"He's been at United for about four years and has bags and bags of ability," stated the defender, also to Posh Player. "He's great on the ball and is probably best in the No10 position.
"He can play centre-midfield as well and is best with the ball at his feet, looking for runners in behind and linking up one-twos. He has shots from outside the box and is a very talented player."
As regards his own move, a return to the Championship club, he added: "Yesterday morning, I was called into the manager's office and he said Peterborough wanted to take me back. That was it really. Obviously, I knew the players, the staff and the club and I know they like to play the right football so I was interested straight away."
