Chelsea's 14-match unbeaten run came to an end on Saturday as West Brom smashed the Blues 5-2 at Stamford Bridge. Chelsea were in control when USA winger Christian Pulisic put them ahead midway through the first half, but it all turned around when Brazil defender Thiago Silva was sent off a few minutes later for a second bookable offence. With the homeside down to 10 men , West Brom mounted pressure and they got their reward via Matheus Pereira who bagged in a double late in the first half to make it 2-1 to the awayside. Mason Mount came off the bench to give his team a boost but the move didn’t do much, with Callum Robinson finishing off a well crafted team effort moments later. Then Mbaye Diagne made it 4-1 with a well-executed strike before Mount scored a consolation goal.

In the end Robinson's late goal sealed all three points for West Brom. After the loss, Thomas Tuchel told BT Sport that he didn’t see the unraveling of his Blues coming. The German said: "There was nothing so much until the red card came. After that we were unable to cope with the situation. I don't know why.

"We gave away two very easy goals. What could go wrong went wrong after the red card. We have to accept the big loss. We did big mistakes before the two yellow cards. There were too many easy ball losses. It was impossible for us to accept the situation.

"Every shot was a goal from them. Clearly it was not our day today. We will get the right response. First of all it's important we digest it. I did not see it coming, now we have to take our responsibilities - me included - and shake it off." Chelsea goalscorer Pulisic, added: "It was a tough first half for us. We made some simple mistakes we don't normally make. The red card changes everything. To give them credit they played their attacks really well. It's no time to panic. We've been in good form and lost one game. We need to be ready for midweek."
