Arsenal legend David Seaman isn't convinced by manager Unai Emery's system.

Seaman admits he is "worried" about the Gunners' new style of play and believes it could take one season for the players to fully adapt to Emery's football philosophy.

He told the London Evening Standard: "Going forward we're great - we've got good, strong players. It's just that, in that defence, we're looking a little bit uncomfortable with the backpass.

"Petr Cech has been highlighted as though he is messing it up but he's also getting backpasses onto his right foot yet he's a left-footed goalkeeper so the defenders need to think about that.

"At the moment, the plan isn't working. You just need to mix it up with a few long balls and then play it out from the back. It looks like they've been told to just play it out from the back no matter what. It's not working at the moment.

"It will take time, there's no doubt about that because the players who are there now aren't all Emery's players. He needs to get the best out of them and then see what he needs to add to the team. That doesn't happen overnight.

"Going into next season, that's when you might see the best of it. At the moment, the Arsenal fans aren't willing to wait that long - they want it now!

"But this way of playing out from the back worries me. We're not confident with it."
