Chelsea boss Thomas Tuchel admits he was left stunned by their collapse after losing 2-5 at home to West Brom.

Tuchel says they collapsed after Thiago Silva's dismissal.

He said, "It is two games, 11 v 11 and then 11 v 10. There is no need to concede five goals when you have our quality, that's for sure but we are all in on that. Myself included.

"We could not adapt to the situation which is a surprise as we were leading. We are normally confident enough to defend but we were sloppy and kept making big mistakes. We were punished hard and it's tough to digest.

"I didn't see the red card, I saw the two big mistakes in our own half before the yellow cards. That is not typical for us, we were rusty. We made easy mistakes and were punished. It was totally our fault.

"I did not see that second half coming. We tried to give a bit of security with a back three but we were never in a flow. We had some chances but we didn't defend well."

Tuchel insists everything went for West Brom on the day.

"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."
