Pep Guardiola’s men were ahead inside 20 minutes when Gündogan turned away from Thiago Silva and angled an inch-perfect drive into the bottom corner from just inside the box.
A breathtaking opening 45 from City continued apace just after the half hour when Raheem Sterling struck the post following a swift counter, but the ball fell at the feet of De Bruyne who duly added a third.
Things could have got even better just before the hour when Rodrigo got on the end of De Bruyne’s floated free-kick, but the Spaniard’s header forced an excellent reaction save from Chelsea stopped Edouard Mendy.
With the game in its dying embers, Chelsea grabbed a consolation in stoppage time when Callum Hudson-Odoi slid in at the back post to put away a low cross from Kai Havertz.
But the damage had already been done as we marched on to a third consecutive Premier League victory, and made a real statement to our title rivals.
