Arsenal outclassed Chelsea 3-1 at the Emirates Stadium last night, to return to the top of the Premier League.
Arsenal are now two points clear of City having played two games more than their title rivals.
The Gunners had gone four league games without a win and were heavily beaten last time out at the defending champions Manchester City.
Chelsea, who fell to a sixth straight loss under interim manager Frank Lampard, were thankful to goalkeeper Kepa Arrizabalaga that the scoreline was not even more embarrassing and even pulled one back through Noni Madueke.
