Cuadrado was playing in midfield against Samp, defensively. You could argue that Chiesa's best position is the same, RM in a 4-4-2.
In attack, he just provides width so Dybala/Kulusevski has the half-space open, and the defensive line is stretched.
I could see Chiesa playing this position. The only area he would certainly trail Cuadrado is in defensive transition, as Cuadrado is probably one of our smartest players in transition, immediately finding the weak spaces in our shape and running into them.
But on the other hand, Chiesa offers the attacking work rate to play *sometimes* in the AM position that Ramsey and Kulu were playing. Will he score a curler or provide 6 key passes, probably not. But he could attack the spaces at least.
Really, if you sign both Gosens and Chiesa, the team looks really strong.
