Chelsea hosted Sam Allardyce’s West Bromwich Albion side at Stamford Bridge, in what was the first game since the end of the International Break.
Thomas Tuchel made eight changes to the side that defeated Sheffield United in the FA Cup.
However, the most prominent of all the changes was the return of defender, Thiago Silva, after spending some time on the treatment table.
Chelsea went out guns blazing against a very defensively coordinated Baggies side, as Sam Allardyce’s men hoped to pounce on the counter.
And so it was that in the 27th minute, Christian Pulisic scored his first Chelsea goal under Tuchel to give the host the lead. However, things went downhill from there, after Silva picked up a second yellow just after 29 minutes of play.
Tuchel briskly made a change, taking off Hakim Ziyech for Christensen, as he hoped to rejuvenate his defence.
The game swung West Brom’s way after former Chelsea defender, Branislav Ivanovic went off injured and was replaced by Callum Robinson. The substitute would go on to score the Baggies’ third goal after two fine finishes from Pereira had turned the game on its head.
With 19th placed West Brom finally in the groove, it was one way traffic from there, as Diagne added to the tally to bury any hopes of a Chelsea comeback.
Mason Mount turned in Timo Werner’s fine pass just three minutes after Diagne’s goal to give the home side a lifeline but substitute, Callum Robinson put another past the hapless Mendy at the death to make it 2:5.
