bump - what is the actual injury? this is bizarre
I don't think it's ever been revealed. Just something they spotted in the medical that wasn't enough to put us off buying him.
He didn't play in Aberdeen's last 3 games so maybe that was due to injury.
I got the impression from what Klopp has said about it that it's more that they've spotted something in the medical and want to prevent it becoming a problem down the line, that he's probably doing some work on his own, maybe physiotherapy and strength and conditioning work to work on whatever his issue is and he'll join in team training in good time.
