Erling Haaland fired Manchester City to the top of the Premier League by beating West Ham 3-0, while Chelsea fought back to salvage a 2-2 draw at Newcastle on Saturday.
Arsenal can retake top spot for Christmas when they visit Everton later, but City ramped up the pressure on the Gunners with a seventh consecutive win in all competitions.
The Hammers feared a rout when Haaland smashed home after just five minutes.
