This Chelsea loss has thrown me, I was gonna be all confident and go for a big Arsenal win at the weekend because I thought Wenger sounded genuinely pissed off to lose against City and would have his team fired up after 9 days rest but a Chelsea loss in the cup means Mourinho would fire his team up now too and demand a response. So yeah impossible to call although Chelsea have an unbelievable record against us. The bookies have Arsenal as the tiniest of favourites so maybe I'll stick with an Arsenal win!
