Arsenal Football Formation

Lineup (4-2-1-3)

Szczesny · Koscielny/Mertesacker · Vermaelen/Djourou · Santos/Gibbs · Sagna/Jenkinson · Song/Coquelin · Arteta/Wilshere · Rosicky/Ramsey · Podolski/Arshavin · Walcott/Gervinho · van Persie/Giroud

I have named 2 players for every position, the second player is the one whom I feel will play fewer games, although the difference in number of games varies depending on position.

Of the players on this list who might possibly leave (although I believe all of them will still be there come September), here are the following solutions:

Arshavin - Switch Gervinho to LW, Giroud to RW, and keep Bendtner
Song - Replace with M'Vila
Walcott - Switch Giroud to RW and keep Bendtner
RvP - Bring in Bendtner

In the event of extreme injuries, I have also listed a 3rd team of unique (outfield) players below:

Yennaris (RB)
Bartley (CB)
Miquel (CB)
Angha (LB)
Frimpong (DM)
Denilson (CM)
Diaby (AM)
Ryo (LW)
Oxlade (RW)
Chamakh (ST)

I am not in the know regards to the GK situation. Depending on how many keepers leave, I reckon Martinez would be a good 3rd keeper, but having a second keeper with more experience would be preferable (or keeping Fabianski or Almunia)
