It was a sprint with consequences: Marco Reus was racing goalbound at full speed when he was tripped and knocked off balance by Tin Jedvaj – not a reproach to the Bayer defender! – in the 41st minute.

Reus' strides became longer and longer, putting his muscles under increasing strain. The striker attempted to take one last stride forward in the hope of beating Leno in the Bayer goal. After briefly receiving treatment on the pitch, he hobbled off and passed the captain's armband to Sokratis.

No precise diagnosis has yet been made but according to the medical department, there is no hope of the agile attacker featuring when Borussia Dortmund play host to Benfica in the Champions League last-16 return leg on Wednesday.

"It's a real blow," said Thomas Tuchel. "In the opening stages today, Marco was the one who constantly got us going, who took the responsibility, who was alert. He has been incredibly stable for weeks now, he's been playing at a high level and is an important character to have on the pitch. The fact he can't play on Wednesday is an enormous loss and takes the shine off the win." (br)
