As much as I think he's overrated, I definitely agree that it's stupid to play the same way with midfielders that can't cover as much ground.
Leaving his role for us aside, I'm not sure if you've seen him while he's been at PSG?
Eight games played. No goals conceded. Eight wins.
They've lost two of the three matches he hasn't played in IIRC.
He's immediately added balance to that PSG side. He doesn't just sit - it's actually Paredes/Marquinhos who is doing that, he's basically playing in a box-to-box role and thriving.
Honestly, he's proving just how good he is.
Last game, against Angers (second at the time they played) I covered PSG. He was ace.
The stats support it too. In no way overrated now. He's genuinely up there with the best in Europe in that position right now.
