Is this what I think will happen or what I would like to happen?
If it's me guessing what will actually happen over the next year and a half:
Players leaving: lindegaard, Ferdinand, evra, Fabio, buttner, nani, kagawa, Anderson, giggs, Hernandez, Rooney, van Persie. We might even cut our losses with Fellaini by then
Ferdinand and giggs retiring, evra going back to Monaco, Anderson probably leaving wherever, same with Fabio as contract is up, nani looks like he'll be sold, kagawa and Hernandez to look for first team football and then one of Rooney or van Persie if we don't make champions league football, both are getting to the end of their primes and won't want to be part of a rebuilding process.
Players coming in: backup keeper, 2 CB's (astori, someone else), 2 left backs (coentrao, Alex Sandro? ), 2 starting centre mids (gundogan, Matuidi?), 2 wingers and a striker, maybe 2.
Obviously this is an unrealistic amount of players leaving and all that, but for all of them you can see leaving within the next few transfer windows, and the only ones I'm sure moyes would really like to keep are Rooney and RVP, the others he probably won't care too much if they go.
So our squad for the start of the 2015/16 season if most of the above leave:
Goalkeepers: De Gea, Lindegaard/new backup, Johnston
Fullbacks: Rafael, new RB, Coentrao, Alex Sandro
Centerbacks: Jones, Evans, Smalling, Astori, Mangala?
Center mids: Gundogan, Matuidi as starters, Carrick, Fletcher, Cleverley, Powell all cover
Wingers/Attacking Mids: Januzaj, Kagawa (hopefully), Koke? as starters, Young, Valencia, Zaha as cover/squad players
Strikers: Welbeck, 1 top class striker, 1 young squad option with a lot of potential (wilson?)
So for a semi-realistic starting lineup at the start of the 2015/16 season:
De Gea
Rafael - Jones - Evans - Coentrao
Gundogan - Matuidi
Koke - Kagawa - Januzaj
Welbeck
Simple, get it done Moyesy.
