Arsene Wenger has revealed the latest team updates ahead of Tuesday night's Capital One Cup fourth-round clash against Sheffield Wednesday:

on the team news...There are no new problems from Saturday, Per Mertesacker is available again after illness. Nobody else is coming back. Arteta will not be fit. Ramsey, Wilshere, Welbeck and Rosicky of course are all out too.

on who will play in goal... Ospina is still out too, so Cech will certainly play.
