Borussia Dortmund beat Chelsea thanks to a stellar goal by Karim Adeyemi in 

their Champions League round of 16 first leg at Signal Iduna Park on Wednesday night.

Chelsea, who had a new-look XI for the Champions League after a busy

January transfer window and the return of some injured players,

looked strong in the first half and saw Joao Felix miss a pair of chances to put his side in front during a scoreless opening 45 minutes

Germany international Adeyemi put Dortmund in front midway through the second half with a brilliant individual effort

picking up the ball at midfield, outrunning his marker

round Kepa Arrizabalaga in the Chelsea goal and slotting home for the lead.

The teams will meet again on March 7 at Stamford Bridge for the decisive second leg

We dominated the first half

They had chances, but we were in control for the majority of the first half

said Dortmund captain Jude Bellingham. "In the second half we took the foot off the gas and they had more control.
