Yeah, I had the same objection with the Mane comparisions when Scouse was making them. Mane's game was so much more than dribbling - his control and movement in tight spaces and tight dribbling there was very good, even before Klopp. I believe it was stated somewhere that it was part of the reason why they were so eager to get him.
Sarr isn't that. He seems more of a direct dribbler, albeit a very good one. Not to say that he can't build that aspect of his game, but the Mane comparisions don't make sense//
