LONDON - Manchester City returned to winning ways and restored their Premier League lead to 15 points with an emphatic 3-1 victory over Watford at their Etihad Stadium stronghold on Tuesday.

As Tottenham Hotspur moved back into fifth, leapfrogging London rivals Arsenal with a 2-0 victory at bottom club Swansea City, Manchester City marched on as in-form Raheem Sterling set up their win with a goal after 38 seconds.

Swansea’s plight under new manager Carlos Carvalhal looked as precarious as that now also facing West Bromwich Albion’s Alan Pardew, as Andy Carroll scored twice in West Ham United’s 2-1 comeback win over the Baggies.

Crystal Palace’s revival under Roy Hodgson continued apace as they also came from behind to win 2-1 at Southampton and pull clear of the relegation zone.

Manchester City’s relentless charge after a record 18 straight league triumphs may have been checked in the goalless draw at Palace on Sunday but normal service was resumed by the unbeaten leaders with dramatic swiftness.

Sterling scored his ninth goal in nine home league matches, tapping in Leroy Sane’s cross as Watford were caught napping in the opening seconds before Christian Kabasele sliced an attempted clearance into his own net in the 13th minute.

Sergio Aguero sealed the victory in the 63rd minute before a late Watford consolation from Andre Gray.

The win put City on 62 points from 22 games, 15 clear of their cross-city rivals Manchester United, although champions Chelsea have the chance to go second, albeit still 14 points behind, if they win at Arsenal on Wednesday.

Fixture complaints

Still, though, City’s Pep Guardiola was not in the mood to celebrate as he chose the aftermath of City’s fourth game in 11 days to lead a chorus of complaints from managers about the congested festive fixture list.

"We’re going to kill the players. The federations don’t think about the players but they have to. They play 11 months in a row. They have to protect them and play with quality and not quantity,” the Spaniard said.

Palace continued to climb the table under Hodgson after second-half strikes from James McArthur and Luka Milivojevic overturned Shane Long’s first goal in 11 months for Southampton.

In the fight for Premier League survival, Swansea and West Brom can now see an alarming gap opening above them as they both sit on 16 points, four behind 18th-placed Stoke City.

Swansea succumbed to Spurs at a drenched Liberty Stadium even though the visitors chose not to start with Harry Kane, who had been suffering from a heavy cold.

Instead, it was his replacement, Spanish international and former Swan Fernando Llorente, who put Maurico Pochettino’s well-rested side ahead with a header which was offside.

When Spurs finally unleashed Kane midway through the second half, his brilliant through ball set up Dele Alli to seal the victory and end the Welsh side’s belated resurgence.

West Ham moved out of the danger zone - to 16th on 21 points - thanks to Carroll’s first goals of the season, capped by his 94th-minute winner at the London Stadium.

Southampton are 17th, also on 20 points alongside Stoke, while Palace, rock bottom for so long at the start of the campaign, moved up to 14th on 22.
