Sam Allardyce continued his impressive record against the Blues, with this victory ensuring he became the first manager in Premier League history to leave Stamford Bridge with all three points with a trio of clubs – having previously done it with Bolton and Crystal Palace – and it ensured the Baggies recorded an away win against us for the first time since 2015.

It was a disappointing day all round for Chelsea and this defeat means our impressive unbeaten run over West Brom (seven games, four wins) ended abruptly. It also put claim to our 17-game unbeaten home run against the West Midlanders in all competitions, which had dated back to November 1983.

Tuchel’s Chelsea finally breached

It took a long time to happen, but the Blues were finally defeated under Thomas Tuchel. The damage occurred in first-half injury time, with the Baggies capitalising on Chelsea going down to ten men following a second yellow for Thiago Silva.

Like London buses, the two goals from Matheus Pereira came in quick succession. In fact, just two minutes and 46 seconds separated each of the Brazilian’s strikes which turned the game on its head.

Those two goals came like a flash and were in stark contrast to the Chelsea rearguard we’ve come acclimatised to under our German head coach. We had previously not conceded in any of our first 674 minutes at home under Tuchel in all competitions before that quickfire brace.

West Brom take their chances

It’s fair to say the Baggies were utterly ruthless at Stamford Bridge yesterday, with Callum Robinson again proving a thorn in our side.

Sam Allardyce’s men really got their tails up once Thiago Silva was dismissed and impressive finishing from Pereira and Robinson did the damage.

The visitors only had 34 per cent of the possession but when they counter-attacked, they did impressively. The Baggies recorded seven shots on target, of which five found the back of Edouard Mendy’s net.

Chelsea on the other hand were more wayward with our finishing, with 18 recorded attempts and only two goals to show for our efforts.

Mount impresses again

Mason Mount came off the bench for the Blues at half-time, replacing the injured Christian Pulisic, and managed to get himself on the scoresheet.

The midfielder was in the right place at the right time to touch home after being unselfishly set up by Timo Werner, ensuring that this crazy game would go right to the wire for the final 20 minutes or so.

Although we couldn’t find a way back into the match, you’d expect that Mount’s telling contribution from the bench will give him a fighting chance of starting our Champions League quarter-final first leg against Porto on Wednesday evening.
