Manchester City swept to the top of the Premier League on Saturday with a 4-0 rout of Southampton as Erling Haaland extended his incredible scoring run to 10 successive games, while resurgent Chelsea eased to a 3-0 victory against Wolves.

Joao Cancelo, Phil Foden and Riyad Mahrez all netted for Pep Guardiola's side before Haaland added his customary goal to seal yet another one-sided success at the Etihad Stadium.

Haaland has scored an astonishing 20 goals in his first 12 competitive games since his £51 million ($56 million) move from Borussia Dortmund.

The champions are now two points clear of second placed Arsenal ahead of the north London club's clash with Liverpool on Sunday. Guardiola's remarkable team have only lost one of their last 37 league games as they chase a fifth English title in the last six seasons.

At Stamford Bridge, Chelsea racked up a third win in new boss Graham Potter's four games since replacing the sacked Thomas Tuchel.

Potter made seven changes after the midweek Champions League victory over AC Milan, with Reece James, Raheem Sterling and Pierre-Emerick Aubameyang among those rested.

Showing the depth of their squad, Chelsea took the lead when Kai Havertz netted three minutes into first half stoppage-time with a looping header from Mason Mount's pin-point cross.

Christian Pulisic put Chelsea in complete control with a cute finish after exchanging passes with Mount in the 54th minute. Armando Broja grabbed his first goal for Chelsea with a 20-yard drive in the 90th minute.

Elsewhere, Tottenham are three points behind Manchester City after Harry Kane secured a 1-0 win at Brighton. Antonio Conte's third-placed team won for the first time in three games after losing at Arsenal and drawing away to Eintracht Frankfurt.

Kane struck with his eighth goal of the season in the 22nd minute, the England captain converting Son Heung-min's cross with a glancing header.

Meanwhile, Bournemouth put under-fire Leicester boss Brendan Rodgers back on the hot seat with a 2-1 win at Dean Court. Having won for the first time this season on Monday, second bottom Leicester have now lost seven of their last eight games.
