If the manager is so insistent on putting Can in the team, I think putting him on the wing would suit him. That way when he runs with the ball with his non-existent turn of pace he believes he really has, we won't lose the ball in the middle of the park ready to be countered.
Or alternatively just put him in defence where a player of that technical ability should be playing until he improves and then move him into midfield when he's a bit more developed.
Rodgers played Can as a full back, wing back, centre half and central midfielder last season. Thats a clear example of a manager insisting on playing a player without really knowing what to do with him.
Klopp has decided on a position for him and I'm happy to watch him develop there, its better than seeing him in a different position every week.
As for playing him on the wing thats a great idea, why not stick Lucas on the other side?
