Thomas Tuchel looked stunned on the side of the pitch-as Werner missed a sitter- as if he genuinely could not believe what he had seen.
The Chelsea boss shook his head, raised his hands and turned away with a look of total disbelief in his eyes.
It was a pretty amazing miss as Chelsea entered the last quarter of the game – a crucial one in the battle for the top-four places – 1-0 up rather than leading by two goals.
