Everton boss Sam Allardyce admits he's in the market for a new fullback.

Cuco Martina has impressed under Allardyce and the manager is happy.

“It's [Cuco Martina's form] obviously made the need for a full back less desperate, there's no doubt about that," Allardyce admitted.

“But, it isn't his natural position, so I feel that he's filling in and doing an exceptional job.

“When Leighton comes back we only really have one recognised and registered left-back in the squad.

“That might be an area I'll want to consider strengthening if that's at all possible in the January window."
