We only beat Fulham by one goal, which also doesn't tell the gulf in class between the two teams?
It's a London derby with plenty of pride to play for on Chelsea's part.
They still have some excellent players and face an opponent who have to go for the win, which can leave them more exposed at the back.
Arsenal's form isn't great and the more I have watched them in recent months, the more I wonder what all the fuss is about?
Barring injury-time wins over United, Villa and Bournemouth, Arsenal's poor form goes back a lot further than many would realise.
Sure, they are at home and the favourites, but if Chelsea can take what chances they do take, then a positive result is more than realistic.
