Arsenal legend Paul Merson has urged his former side to make two defensive signings in the summer transfer window.
The Gunners brought in Pablo Mari and Cedric Soares on loan in January but neither have made an appearance as of yet.
Should Mari impress there is a chance he will be made a permanent acquisition while Soares is expected to return to Southampton at the end of the season.
Merson strongly believes that Arsenal should bolster their ranks with two new players, specifically one centre-back and a defensive midfielder.
"They need a centre half and a world-class holding midfielder," Merson told Sky Sports .
"I think Arsenal need to play with a back three. They’re not good enough as defenders to play as a four.
"Ake has pace and he’s played in England for a while, so if you brought him in for next season he’s not a player who will need time to get used to the league for six months.
"Arsenal need to hit the ground running [next season] and everybody needs to know their jobs in the team."
