Smalling, Jones, De Gea, Fabio, Rafael, Powell, Welbeck, Cleverley, Pogba (still) and a few others. Those are the realy young - 10-15 years left in the club.
Then there are Nani, Rooney, Valencia, Fletcher (maybe), Evans, Anderson, Hernandez, Young and Lindegaard who can play 5-10 years.
So the future looks great.
But it surely is no news.
