If you have seen compilations of his ajax days, you can see he could dribble past opposition players and shine on a less demanding league, with less pressing than the premier league. If you give him a ball on a training ground without pressure, he probably could do some flicks that would look good on a instagram reel or something. Also, you don't get to be a Brazil international without innate talent because theres hundred of thousands of kids competing for a couple of winger spots.
You can evidence his lack of football iq because he hasnt adapted to the prem in the sense that he always do the same thing over and over again, there's no variation to his game and is so predictable for our rivals. If he had a variety of different solutions he would be unpredictable but as soon as our rivals double mark him you now hes turning back and passing the ball back to our defence.
It's funny how perceptions can vary from one fan to another but i respectfully disagree with your appreciation
