Arsenal manager Arsene Wenger says he has to sell players before even thinking of adding new faces to this squad.
A number of Arsenal players are expected to depart this month including Englishmen Jack Wilshere and Kieran Gibbs.
Defenders Carl Jenkinson and Cohen Bramall have left the club to join Birmingham on Monday but other players will follow before the end of the month.
"I expect to sell players first," he is quoted as saying by Arsenal's official website
"That's all. I expect some players to go because we have too many players and it's not manageable.
"Many clubs are in this situation which is why the transfer market is quiet. We have 33 players at the moment, and that's too many players."
