You really don’t rate him. He’s proven over the years how good a full back he can be
In the same way Zinchenko and Delph did.
He plays LB because he’s not even close to Walker at RB.
And Pep spent all summer chasing a £60m left back because he didn’t want to play Cancelo at LB.
There’s been a few spells where his attacking output has been incredible and made all the other problems worthwhile.
But they’re few and far between and he’s a MOTD highlights player 90% if the time with at least one massive rick in him per game.
It’s not a coincidence we got to the CL final when he was benched for bad form (after being hooked at half time in the quarterfinal for doing his best to cost us the game)
