9 points and +7 GD ahead of City with 7 fixtures left to play, and they have one extra in hand.
Assume the worst case about two things: they win their fixture in hand and they beat us at the Etihad.
Then we can win the league if we can drop no more than 3 points and +4 GD on them over the other 6 fixtures.
Arsenal: Bournemouth (H) … Newcastle (H), Fulham (H), Hammers (A), Burnley (H), Palace (A).
City: Chavs (A) … Burnley (A), Everton (A), Brentford (H), Bournemouth (A), Villa (H), Palace (H) - postponed
We've been in this situation before and City achieved a perfect record of wins. Now that's effectively what they'd need to do to beat us to the title. But since they have done it before … it's far from over.
