Fergie said: "Gabriel is a player we have tracked for a few years now, but because of his educational programme our efforts to get him here have always been delayed. We are delighted to get him now as he is an exciting prospect. We like to get young players and develop them, and we will see that in Gabriel over the next two years."
Obertan had this to say: "I am very happy to join Manchester United. This is a big opportunity for me to play at such a great club. I am very excited to be here and I look forward to proving what I can do."
Fingers crossed.
