Here are a few very serious young ballers to keep an eye out for. Very impressive.
Isco (Spanish) Malaga, arguably the best of the lot. Technically Smooth, imaginative & creative in possession.
Quintero (Colombian) Pescera, loves to run at opponents & can beat very exciting
Cuadrado (Colombia) Fiorentina, Wide right player very exciting, love to beat but very modern in terms of understanding his responsibility.
I also like a forward Léo Baptistão (Brazilian) playing for Real Vallacano, he did some serious stuff but I have not seen enough of him.
