Borussia Dortmund defeated Chelsea 1-0 in a Champions League round of 16 first leg on Wednesday night.
Karim Adeyemi’s brilliant breakaway goal for means the Blues head into the second leg with a deficit.
Graham Potter’s side had the better chances amid a boisterous atmosphere in Germany but Thiago Silva had a goal disallowed for handball and Joao Felix hit the crossbar when well placed. Ademeyi’s solo run punished their earlier profligacy just after the hour mark.
It was cruel on Chelsea given their performance. Once behind they pushed hard for the equaliser and came close when Kalidou Koulibaly had his fierce shot cleared off the line by Emre Can. But they must now come from behind at Stamford Bridge to progress.
The defeat on the night means that Chelsea have now won only once in nine matches since the turn of the year and though Potter will have been encouraged by some of what he saw, this was further evidence that this is a team still finding ways not to seize victory.
