This kid doesn't look like Vinicius to me. Vinicius looks infinitely more intelligent at the same age and loves a good run in behind the line, which is proven by his role in the U-17s. Rodrygo looks to have this tunnel vision common for youngsters and tends to faff around on the ball, which TBF he's quite good at. He dares to go into tight spaces and comes out of them nicely. The way he drops into the centre reminds more of Kaka than of classic wingers. Positionally he likes to do the same things Odegaard does, isn't anywhere near as smart for the age, but can compete with older defenders with decent balance and fearless contact game.
Problem with guys like Rodrygo is that they don't fare well on the continent when they have to give up the ball in a system. Not sure if it's worth spending 50M on him just to upend Barca's hopes for him, but why not? Better to invest than to do nothing.
