Speaking on Thursday morning, Liverpool manager Klopp revealed that Coutinho’s injury is the more serious of the two and that the Brazilian playmaker is out until February, while Lovren will be sidelined for at least 10 days.

“Coutinho is more serious than Dejan,” revealed Klopp at his media briefing on Thursday. “Kolo is only cramp but it won’t be possible for him to play the next game.
