Don't worry about that, we'll give them a real game next week. Van Persie and Gervinho have really hit top form these last 2 weeks and they have been absolutely unplayable. Ramsey is getting better and better while Arteta and Song have done their job at the back. Koscielny has pulled out good defending from his ass and he's been really good these past 2 weeks too while Mertesacker is settling. The only question mark for me is Walcott because he hasn't looked good enough so far and Arshavin and Rosicky will be pushing for a place because they have looked reborn lately too.
I'm not really worried about Arsenal, I know we can play well, it's Chelsea's defence that is the biggest concern. Ivanovic, Luiz, Terry and Cole is a great defence and I don't know whether Gervinho, RVP and Walcott/Arshavin can get past them. Ramsey will need to have a great game to break through to the forwards. Chelsea's midfield is strong too and Sturridge, Torres, Mata upfront will be a real handful for our semi-makeshift defence. Should be a good game!
