Manchester United winger Gabriel Obertan was aware they were following his progress at Bordeaux for some time.
The French winger has only just started playing first team football for United after recovering from a back injury.
He told manutd.com: "I knew United were interested because Jim Ryan (head of youth development) came to watch me play four years ago.
"I knew there was interest there but I didn't expect the move to happen so early in my career. But I felt ready for it, I knew I was ready for the challenge and the change in my life. It was like a new beginning for me and I am just glad to be here and have the opportunity to play for this great club.
"I've always liked English football. When I was in France I would watch English football every weekend. And I think you're right, for my qualities I believe this is the best league in Europe for me. I'm quite fast and I like to attack and be in one v one situations with defenders."
