Let's just beat Chelsea, then there's so much pressure on the Tottingham in the norf landan derby. Lose that and stay 9 points adrift with 5 games to play and having City in the next game might just be a bit much for them.
Mind you, even if we lose to Chelsea if Arsenal give them a good shoeing following by the same against City they'd have to make up 6 points in 4 games. Two of which would be another london derby against Chelsea and a tough game against Liverpool.
