Manchester City moved a commanding 13 points clear at the top of the Premier League after beating title rivals Chelsea at the Etihad Stadium.
Kevin De Bruyne curled home the decisive goal from 25 yards with 20 minutes of the contest remaining to reward a dominant display from Pep Guardiola's side.
Third-placed Liverpool, who have two games in hand, including Sunday's match at home to Brentford, are on 42 points but City have streaked clear.
It was a fine solo goal from De Bruyne which settled the outcome, the Belgian riding a challenge from N'golo Kante before beating Kepa Arrizabalaga with a curling shot into the far corner.
