Manchester City reignited the Premier League title race on Sunday, scoring three goals in 17 second-half minutes to crush Chelsea at Stamford Bridge and move within six points of leaders Arsenal.

Nico O’Reilly started the rout, shrugging off Andrey Santos to head the ball home from a Rayan Cherki cross in the 51st minute. Cherki was on hand six minutes later to cross for former Chelsea defender Marc Guehi to finish in the bottom corner.

Jeremy Doku made it three in the 68th, robbing Moises Caicedo of the ball just outside the Chelsea area and flashing his shot past the stranded Robert Sanchez in goal.

City, who have a game in hand, play Arsenal, who lost to Bournemouth on Saturday, next weekend with their tails up, but the result severely dented Chelsea’s Champions League qualification ambitions. They remain sixth, four points adrift of Liverpool in fifth.

Tottenham mired in relegation zone after defeat at Sunderland

Tottenham Hotspur’s relegation fears deepened as manager Roberto de Zerbi’s first game in charge ended in a 1-0 defeat by Sunderland that left the London club third-bottom of the Premier League on Sunday.

It was a familiar tale of woe for Tottenham as Nordi Mukiele’s wickedly deflected shot just past the hour mark sealed their fate and gave Sunderland a deserved win that boosted their European ambitions.

Tottenham showed battling spirit but not a great deal of attacking quality as their winless league run stretched to 14 games, their worst since 1935 when they were relegated.

They have 30 points from 32 games, two behind West Ham United who are one place above the drop zone. Sunderland’s first Premier League win against Tottenham since 2010 left them in 10th with 46 points, two behind sixth-placed Chelsea who are in action later at home to Manchester City.

If it had not already dawned on Tottenham fans that a first relegation since 1977 was looming large, West Ham’s thrashing of Wolverhampton Wanderers on Friday to leave Tottenham below the trap door for the first time this season meant the alarm bells were ringing loudly ahead of the Stadium of Light clash.

Victory would have taken them above West Ham, Nottingham Forest and Leeds United, but it rarely looked likely.

“I cannot say anything to players because they gave their best in terms of attitude and spirit,” said De Zerbi, Tottenham’s third manager this season. “I’m sure if we are able to win a game then everything will change.”
