Arsene Wenger has revealed the latest team news ahead of Saturday's north London derby against Tottenham at Wembley Stadium.

The Arsenal manager provided updates on Petr Cech, Danny Welbeck and Nacho Monreal, and this is what he said:

on the team news…

Basically, we should have a similar squad to what we had last week against Everton. Maybe Danny Welbeck will be back. We had a few problems with Petr Cech, who we are not sure about at the moment because he’s not trained. I don’t know if he will be available. Nacho Monreal looks alright again. It should be a similar squad.

on whether a late call on Cech’s fitness is a risk in this fixture…

I will not take any risk if he’s not 100 per cent fit, for sure, because I have full confidence in David Ospina.

on David Ospina proving he can play in fixtures of this magnitude…

I have no problem with [selecting Ospina]. David Ospina or Petr Cech: I will make that decision tomorrow.
