He isn't even the best Spanish player born in 1993 (that's Roberto Carballés). Boluda-Purkiss has been overrated since he was 12 years old. I think he'll be lucky if he makes the top-100
Well, Carballés was almost a nobody until he won in Oviedo. Let's wait and see.
Boluda was clearly the best player in Europe in his generation when he was 12-15, that's not debatable. Of course predicting the evolution of a player is not easy, the best juniors not always become the best pros but that doesn't change the fact that they were the best juniors.
