Luckily for Arsenal, Gibbs was back from injury and up for the challenge, quickly slotting back into his favoured role after Koscielny was subbed off four minutes into the match.
The French international has only just recently found his way back into the starting eleven after lackluster performances from Andre Santos meant Wenger had no option but to push Vermaelen out to the left and utilize Koscielny in the centre.
Wenger is quoted as saying by Goal.com on Koscielny’s injury:
He has a groin strain. That’s usually three weeks.
While Tomas Rosicky inches closer towards a return, Koscielny joins Abou Diaby, Lukasz Fabianski and Andre Santos on the sidelines, leaving us somewhat short at the back.
The injury comes at a horrible time where Arsenal face a tough schedule in December and Gibbs only recently returning from a somewhat lengthy lay-off with injury.
Hopefully the current back-line are able to remain fit until at least Koscielny returns, this is of course provided his scheduled return is not based on some Diaby-time.
