His playing style is perfect for a 433 imo. Where you need width in that formation thats literally his main game so I think it would suit him more in that position, sort of what Neymar does for Barca except at an obviously lesser level.
That's not how a normal 4-3-3 works at all mate. The natural width comes form the fullbacks with the two wide men upfront always cutting inside to play as inside forwards. That's why in all the top clubs the wide forwards are "inverted" with left-footers on the right and right-footers on the left
- Barca with Neymar, Suarez, Messi
- Juve with Mandzukic, Higuain and Dybala
- Bayern with Ribery, Lewa and Robben
- Real with Ronaldo, Benzema, Bale
In all these teams the players surrounding the striker are actually cutting inside almost always. Hardly ever will they race down the touchline to put a cross in the box. That's the job of players like Alba, Dani Alves, Carvajal, Marcelo, Alex Sandro etc.
I'm not saying that a natural wide man up front could not work in a 4-3-3, I'm not a coaching expert. I'm just saying that if all the top teams play with inverted forwards there must be something in it.
