Rodrygo is a very hard worker. Sacrifices for the team, will play a support role if necessary. He's also a good playmaker. Can cut inside and play a pinpoint throughball to a runner, and his cutbacks actually go to teammates. He's a fantastic finisher. Curlers to the far post, chips and dinks, through the legs, powering into the roof of the net, guy has every technique other than heading.
My biggest concern would not be his quality or ability, but his mentality. Can he handle leaving Madrid? Can he deal with the frustration of PL football, which is refereed bizarrely such that players like him are inherently disadvantaged?
