Jordan Henderson suffered a knee injury in Liverpool's 1-1 draw at Borussia Dortmund, souring a memorable return for Jurgen Klopp.
Jurgen Klopp voiced fears over Jordan Henderson's fitness as a knee injury to Liverpool's captain took the shine off the manager's return to Borussia Dortmund.
Liverpool struck first in the Europa League quarterfinal at Signal Iduna Park through Divock Origi's goal nine minutes before halftime.
But the club Klopp coached with distinction for seven years leveled through Mats Hummels' header early in the second half and it remained 1-1 for next week's second leg at Anfield.
