Arsene Wenger admits that the form of his current starting XI is going to cause him a problem.
Arsenal have recorded nine straight victories which means the likes of Gilberto Silva and Lassana Diarra may be left kicking their heels on the sidelines.
"In our job there is always competition," said Wenger ahead of their weekend clash with Sunderland.
"It's not because you don't select a player that you don't respect him.
"For example Gilberto doesn't play at the moment. I have a huge respect for Gilberto, for the man and the player.
"But at the end of the day you can only select 11 players to start a football game, and it's part of our job to deal with that as well. You feel sorry but you have as well to be realistic.
"I have 23 difficult decisions because all my squad I can play - Diarra for Flamini, or Gilberto or Denilson. They are all top-level players and every decision is difficult to make, but I consider how the team goes at the moment and how they will play."
Wenger actually hopes to have his entire squad back in training next week - which will mean Jens Lehmann, William Gallas, Tomas Rosicky, Alexandre Song and Eduardo da Silva all making welcome returns.
"Jens Lehmann and William Gallas are already back in full training," added Wenger.
"Tomas Rosicky and Alex Song should be back on Saturday. Eduardo should be back on Tuesday."
