League leaders and defending champions Manchester City defeated closest rivals Chelsea by a lone goal and thereby open a 13 point gap which will be reduced to 11 points if Liverpool can take all three points against Brentford.
Mid-field maestro Kevin de Bruyne scored the only goal with 20 minutes left in the game.
Chelsea failed to convert their chances and paid for it when the former Chelsea man curled his effort past keeper Kepa Arizebalaga.
Manchester City deserved to win after having 56% of possession and making six attempts on target as to Chelsea’s one.
