Arsenal boss Arsene Wenger is unsure if Petr Cech will be fit for Saturday's derby at Tottenham.

The goalkeeper collected a knock in victory over Everton last week.

Wenger said this morning: "We should have a similar squad to Everton. Maybe Welbeck will be back.

“We are not sure with Cech, he has not practised. I don't know if he should be available.

“Nacho Monreal should be alright."

He added: "“I have no problem.

“Ospina or Cech, I will make that decision tomorrow.

“I will not take any risk if he is not 100 per cent for because I have full confidence in David Ospina."
