Former Arsenal striker Kevin Campbell says Shkodran Mustafi's time at the club is over.
The German has endured a tough season and was given a hellish time on Sunday by young Everton striker Dominic Calvert-Lewin, who lead his side to a 1-0 victory.
Campbell told Stadium Astro: "I've said it all along, he's done okay at times but moving forward, I think Arsenal need a centre-back. I really think they do.
"Rob Holding I think is a very good player. He's been out injured so he's to come back.
"They need somebody there. [Dominic] Calvert-Lewin caused too much trouble, on his own.
"They need a quick one. A quick centre-back who can run and read the game."
