Former Arsenal star Stewart Robson believes the club should target Bournemouth defender Nathan Ake.
Chelsea have a buy-back clause to bring the Dutchman to Stamford Bridge.
Regardless, Robson thinks Arsenal should challenge their rivals to sign the talented defender.
He told Love Sport Radio: "I still think Nathan Ake is good player.
"There's talk about him going back to Chelsea because they can buy him for a certain price but he's a very good centre-half.
"He's not the biggest but he's got good spring and I think he's the type of player [Mikel] Arteta will like.
"He would be my choice coming in from Bournemouth."
