Arsene Wenger has revealed the following team news ahead of Saturday's game against Sunderland:

on Kieran Gibbs…Kieran is a few more weeks away. Still four to six weeks really.on Laurent Koscielny and Thomas Vermaelen…Koscielny had a scan that was quite reassuring so he will have a test today [Friday]. It is a calf problem. Vermaelen is out with his ankle injury.on defensive options…The options are restricted, I will have to be creative. We have Iggy Miquel, we have Sagna who can play there and Jenkinson on the right, so we will see. But we have very good hope that Koscielny will be available.on Francis Coquelin and Aaron Ramsey…Francis still has a little pain at the back of his hamstring. I don’t think he will be with us on Saturday but I’ll have to check that today [Friday]. Aaron Ramsey is OK.on Gervinho…Gervinho has arrived back [from the Africa Cup of Nations] on Friday but he is not in the squad for Sunderland. We have given him five days off.
