After some near misses in the first half, Raheem Sterling gave the host the lead in the 43rd minute, before a retaken Kai Havertz penalty eight minutes into the second half sealed it.

Jude Bellingham missed an excellent opportunity to score for the visitors shortly after Havertz's penalty as the Bundesliga side toiled in west London after losing Julian Brandt to what appeared to be a hamstring injury early on.

It was Dortmund's first defeat since club competitions stopped prior to the World Cup, having won 10 in a row heading into this game, and was Chelsea's second win in a week as Graham Potter looks to turn their fortunes around.

Havertz almost put the hosts ahead just before the half-hour mark but his shot towards the near post from the edge of the box struck the inside of the woodwork, with the ball going across the goal but not in.

It was Sterling who broke the deadlock before half-time though as Chelsea put the Germans under concerted pressure, with the former Manchester City man getting a big slice of luck as he fluffed his first effort from Ben Chilwell's cross back into his own path, before slamming his second high into the roof of the net.

Chelsea had a penalty early in the second half after Marius Wolf was judged to have handled a Chilwell cross, with Havertz hitting the post with his first spot-kick, before being handed a second chance after a Dortmund player allegedly encroached, which he scored after sending Alexander Meyer the wrong way.

Bellingham skewed a shot wide under pressure from Kalidou Koulibaly as Dortmund failed to find a way back into it against a spirited Chelsea side.
