Premier League leader Manchester City moved ever closer to the title with a 2-0 win at Leicester, while a lowly West Bromwich Albion stunned Chelsea in a 5-2 defeat to hand manager Thomas Tuchel his first loss at the helm Saturday.

Liverpool took full advantage of Chelsea's shock collapse to close within two points of the top four with a 3-0 win at Arsenal.

City is 17 points clear of second-placed Manchester United after a remarkable 15th successive away win in all competitions.

United can close the gap with a win against Brighton on Sunday in the first of two games in hand, but it is only a matter of time before Pep Guardiola's men celebrate its third title in four seasons.

Goals from Benjamin Mendy and Gabriel Jesus killed off third-placed Leicester in the second half at the King Power.

City, chasing an unprecedented quadruple, will go into its Champions League quarterfinal first leg against Borussia Dortmund on Tuesday in a confident mood after avenging the 5-2 thrashing they suffered against Leicester in September.

"It is a big step to winning the Premier League," Guardiola said.

"The Premier League is the nicest competition to win. It is 11 months and it is so tough. We are close."

City controlled possession and its dominance was rewarded in the 58th minute.

Mendy cleverly eluded Marc Albrighton in the Leicester penalty area before curling a fine finish into the far corner with his weaker right foot.

Jesus then converted his fifth goal in his last seven games 16 minutes from time from Raheem Sterling's unselfish pass.

Tuchel calls for calm

At Stamford Bridge, Chelsea boss Tuchel saw his 14-game unbeaten run since replacing the sacked Frank Lampard come to juddering halt.

Christian Pulisic gave Chelsea the lead in the first half, but Blues defender Thiago Silva was sent off two minutes later for a second booking.

Second-bottom West Brom made the most of that gift in first-half stoppage-time as Matheus Pereira struck twice in quick succession.

They were the first home league goals conceded by Chelsea since Tuchel arrived in January, also ending a run of seven successive clean sheets in all competitions.

Shell-shocked Chelsea capitulated in the second half as Mbaye Diagne got Albion's third before Callum Robinson struck twice.

Mason Mount's reply was no consolation for Chelsea, who conceded five at home in the league for the first time since 2011.

Chelsea remains in fourth, but West Ham and Tottenham would both go above them if they win their games in hand later this weekend.

"We cannot lose our heads now and take away the trust we have in these players," Tuchel said.

"It was the moment after the game to be honest, be calm and to tell everybody to breathe. This is my responsibility. I trusted this line-up."

Liverpool back in the groove

City's win meant Liverpool can now not mathematically retain its title, but it is back in the race for Champions League football next season thanks to its first successive league victories since January.

Jurgen Klopp's men looked more like their old selves in a dominant display that got its reward thanks to three goals in 18 second-half minutes.

Substitute Diogo Jota powered home Trent Alexander-Arnold's cross to break the deadlock before Mohamed Salah cleverly prodded the ball between the legs of Bernd Leno.

Jota rounded off the scoring with his sixth goal in four games for club and country.

"We have to win our own games, but in our situation, other teams have to lose games as well," said Klopp.

"We have to keep working, but it is a nice sign. We are still there."

Arsenal remains in ninth with its season now hinging on success in the Europa League after what manager Mikel Arteta described as an "unacceptable" performance.

Leeds moved level on points with the Gunners as it pushed bottom-of-the-table Sheffield United closer to relegation with a 2-1 win in a Yorkshire derby at Elland Road.
