It's only when you look back on last season you realise just how much football he played. I think at the AFCON he played a ridiculous amount of minutes within a short space of time and he's never looked the same since he came back. It's a real conundrum for Klopp. Keep playing him in the hope he finds form or let him have a couple of weeks off on the bench and hope that gives him time to recharge.
Surely the real conundrum is "keep playing him so that he's nowhere near the goal or allow him to get into goal-scoring positions?"
When he has done, he's scored or had decent shots on goal
He can't really bring the ball in from wide and score anymore because every opposition team has trained and set up specifically to stop that.
Alternatively he's showing up as a top chance creator for others so maybe others need to put it in a bit more often and we can celebrate his creativity; team game, remember?
