The Gunners have lost some big days in the past few summer transfer windows including Cesc Fabregas, Samir Nasri and Robin van Persie but the French boss does not believe the same will occur this time around.
"It's a really wonderful feeling knowing everyone I want to stay will stay," he said.
"We have started going to pre-season camps with a player being half in and half out. It's not the best way to prepare.
"We can talk about new signings and I hope we achieve that - but this stability is more important than ¬any new player who comes in."
