Arsenal are expected to sell players before they strengthen their squad in the remaining month of the summer transfer window.
The club has signed Alexandre Lacazette and Sead Kolasinac but will look to sell several players before they consider making any new signings.
Arsenal have thirty three players in their senior squad.
“The number is too high,” Wenger said following their Community Shield win against Chelsea on Sunday. “We will let some players go. Too much competition for places is detrimental, but not enough competition for places is detrimental as well.”
It is understood Arsenal are not in active talks over Thomas Lemar at Monaco but have not entirely ended their interest in signing him this month after a bid was rejected last month.
