Yes his wages are highest so doesn't fit our structure.
Also yes his numbers were unreal in Bundesliga but he failed to translate them in PL for 2 seasons now. Nothing suggests he will change that in the future. We had those examples before especially in Dortmund attack.
Raphinha on the other hand is proven PL player. Did great in both seasons.
Regarding age Raphinha is 26, Sancho and Torres 23 and Fati just 20. So I think Fati has highest selling. 22 goals in LaLiga in minutes equal to 35 games. His biggest problems are obviously injuries. If he puts them behind he can become world class player. I'm ok if we decide to bet on that.
