Liverpool hero Jamie Carragher believes Arsenal need to sell Shkodran Mustafi.
The Gunners defender scored an own goal early on at Anfield and was on the pitch as Arsenal suffered a penalty shoot-out Carabao Cup defeat to Liverpool on Wednesday night.
"I think them days are gone - Mustafi playing in the Premier League," Carragher told Sky Sports.
"He's just one of those defenders. When someone does that it makes others nervous.
"You can't play your own game because you're half covering for him.
"I think once he goes it will be better for everyone at Arsenal."
