Chelsea manager Thomas Tuchel says he “cannot accept” his team performance in their 5-2 loss to West Brom at Stamford Bridge on Saturday afternoon.
The Blues took the lead in the first half through Christian Pulisic, who reacted first to a Marcos Alonso free-kick.
But they were reduced to 10 men soon after when Thiago Silva picked up a second yellow card.
West Brom capitalised on the red card and punished Chelsea netting two goals before
the half-time through Matheus Pereira.
Goals from Callum Robinson and Mbaye Diagne seemed to end the game in the second half.
Chelsea pulled one back through Mason Mount to make it 4-1 but West Brom had the last laugh when Robinson made it five.
The defeat ended Chelsea’s 14-game unbeaten league streak under the German.
speaking after the loss, he told BT Sport “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’s impossible for us to accept this 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’s defense has greatly improved since Tuchel took charge in late January.
But the ease with which West Brom split them multiple times will be of great concern to the German boss.
