Arsene Wenger dismissed the seriousness of a head injury suffered by Per Mertesacker.

“I’m a bit under shock there because we lost our two centre-backs in the game and after we lost Aaron Ramsey.

“Mertesacker is not serious, just a little concussion. I think Gabriel looks right. Ramsey, I’m a bit more concerned because it’s a thigh injury.

“Apart from that we have played well.”
