I think people need to get the idea out of 25 world class players out of their heads. United's squad has won titles with Johnny Evans, Tom Cleverly, John O'Shea, Wes Brown, Kieran Richardson and many others like this.
Personally, I'd take:
Sturridge - obviously, he'd take the 4th spot
SWP - in front of Navas, but that may be because I find Navas impotent. Sinclair if you like Navas
Johnson - in front of Lampard
Barton - in front of Fernando
Richards - in front of Sagna
Mee - in front of Boyata
Schmeichel - in front of Caballero
I'd also take Denis Suarez back as he's impressed me at Sevilla, probably in front of the one out of Navas or Sinclair not picked above.
8 homegrowns and 8 club trained without significantly weakening the squad. Only SWP, Johnson and Barton aren't really available today out of them aswell though I wouldn't take back Mee knowing Denayer is coming back next season
It's worth pointing out by the way that that Burnley side who came here and nicked a point after being 2-0 had more City Academy graduates in it than the Man City team did.
