A superb length-of-the-field goal from Borussia Dortmund forward Karim Adeyemi helped his side to a 1-0 win over Chelsea on Wednesday, putting them in the box seat to qualify for the Champions League quarter-finals.

Adeyemi's goal came during a period of sustained dominance from the visitors early in the second half, with the Germany forward pouncing on a clearance from a Chelsea corner.

Adeyemi sensed the opportunity and ran the length of the field, rounding both Enzo Fernandez and goalkeeper Kepa Arrizabalaga to give Dortmund the lead in the first leg tie.

Dortmund captain Jude Bellingham told German TV when Adeyemi finds himself in space "not many players can really stop him."

"He had a tough time coming here at the start - finding his feet - but now he's flying."

After the match, Adeyemi praised his side's desire to fight for giving them an advantage ahead of March's return leg in London.

"I had a little bit of luck, but I'm really happy about the goal," he said. "Everyone fought for everyone else - (the win) was really important for the return leg."

The win means Dortmund only need a draw in London to progress to the quarter-finals for the second time in the past four years.

Elsewhere, Benfica closed in on a place in the quarter-finals after easing to a 2-0 victory over Club Brugge in Belgium in the first leg of their last-16 tie.

Both goals came in the second half at the Jan Breydelstadion.

Joao Mario opened scoring from the penalty spot six minutes after the restart.
