Jurgen Klopp has admitted Jordan Henderson's injury looks "serious enough" after the Liverpool midfielder was taken off in the early stages of their Champions League last-16 second leg victory over Bayern Munich.

Henderson was hauled off in the 13th minute by Klopp and replaced by Fabinho after continuing to play on following a clash with Bayern's James Rodriguez.

The former Sunderland midfielder appeared to roll his ankle and Klopp hinted he could be facing a spell on the sidelines.

“Hendo’s twisted ankle, we have to see," said the German. “It looks serious enough, and when you have to change in the middle of the park it’s not ideal.

“We didn’t want to ‘rest’ Fabinho but we wanted to bring in fresh legs. Hendo had fresh legs but it didn’t help his ankle!
