Arsenal have done their business in terms of incomings, but Arteta wants to trim his squad down now.
The boss has made it clear that the squad needs to be thinned, speaking at his press conference on Thursday morning. 'We have 30 players here which is not sustainable. And obviously the market is still open and things can happen.'
Having narrowly missed out on the title last season, Arteta will be determined to ensure that he has the right players around him, to back up the major signings of Declan Rice, Kai Havertz and Jurrien Timber.
