Jude Bellingham was quick to highlight the importance of Emre Can to Borussia Dortmund after Karim Adeyemi stole the headlines in the narrow win over Chelsea.
Dortmund will take a 1-0 lead into the second leg of the last-16 Champions League tie after Adeyemi ran the length of the pitch to punish Chelsea on the counter-attack. The 21-year-old forward raced away from the Blues' defence and rounded goalkeeper Kepa Arrizabalaga to score the only goal of the match.
Chelsea had plenty of chances but their poor run in front of goal continued as Gregor Kobel excelled between the sticks for the hosts. Joao Felix, Reece James and Enzo Fernandez had good opportunities, but it was Kalidou Koulibaly who came closest to finding the net.
