The Gunners have been linked with several players but are yet to confirm a single addition to their squad but Goal.com revealed on Tuesday that they are ready to trigger the £3.5 million release clause for West Ham midfielder Mohamed Diame.
The Frenchman cut short his press conference after beating the Hammers 5-1 "to do some work in the transfer market".
"What I worry about is getting the players who have been injured back fit, to get the players who play for this club to perform at full potential," the Frenchman told the press.

"If someone else can strengthen our squad, we will do it, of course, but we have the resources inside to do well.
"We have two players in every position, that should be enough, plus the young players in behind.
"But if we find the top-class players in any position, we never refuse to strengthen our squad."
Wenger also spoke of his dislike for the January window, claiming that it offers an unfair advantage to some clubs.
"I think it should be all completely cut out or limited to two players," he added. "It is unfair for the league that some teams who have played Newcastle twice already have an advantage on teams who [have yet to] play Newcastle, now they have bought six or seven players.
"You do not face exactly the same team so I believe the number of players you could buy should be limited."
