Besides Marcelo, Kimmich is a good crosser, Trent Arnold is one of the best crossers I EVER seen for a fullback. So there are few left.
But I didnt mean Cuadrado cant defend or is too attacking. But it's his role in our set up to cover his whole flank offensively. While the LB is more conservative and mostly tucks in centrally in midfield or for CBs. That's how Sarri likes to play.
Was same in Napoli, Chelsea and now with us, he uses the fullbacks almost in asymmetric way.
