He's still among the very best in the world as a fullback, specially in a team that plays with wingers.
Thing is in the 352, the rwb is supposed to offer width for the team, it's a very important position, and Cuadrado fits better.
I'm all in for Cuadrado as our perennial starter when 352 is being played and when Dybala is playing his natural position - trequartista/ss.
