SAF planning for the future is no news at all. He's always been doing that, and in the current squad, there are several players ready for the future:

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.
