Ex-Arsenal striker Kevin Campbell believes that his former club have not addressed the real problems in their squad during the transfer window.

Despite a high-profile move for Alexis Sanchez and the capture of Southampton youngster Callum Chambers, Campbell still thinks that the Gunners need a new central midfielder and a goalscorer.

Asked if Arsenal are a stronger side than last season, Campbell told talkSPORT: "No, I don't think so to be honest. Alexis Sanchez is a fantastic signing but I don't think the problems have really been addressed.

"I like the Calum Chambers signing but he's going to take a bit of time to bed in. The two main problems were the centre of the pitch and a noted goalscorer, and they haven't addressed that problem.

"If you struggled against the top boys and you don't address the problems, then you can't expect a different result."

According to reports elsewhere, Arsenal are being encouraged to renew their interest in Real Madrid midfielder Sami Khedira.
