Kieran Gibbs is out for three weeks with a hamstring strain which is so very Arsenal. Let's hope Shad and his team are on hand to not turn it into an even more Arsenal two months. Nacho Monreal who did well when he came on last weekend will continue in Gibbo's place. Laurent Koscielny makes the trip which allows big Per Mertesacker his extended rest. New boy Calum Chambers will have another taste of what life is like at a big club with his first Champions League match of his career, even if it doesn't quite count unless you qualify but you know what I mean.
