@Cassidy i recommend a quick youtube check on Ronaldo in Sporting. He was considerably younger and already a game changer. A player who could drag one, two, three players and often break through the lines with the ball on his feet, even without much end product, is invaluable and restricted to a select few. Félix doesnt have that. Sure he has other skill sets like one-twos but he lacks the power and acceleration to ever reach levels of a great like Ronny, Messi, etc.
He can become a very classy trequartista type of player like Pastore but those sort of players aren't easy to fit into modern game. Benfica isn't a good example to go by as been said many times.
Totti was much better than Félix at his age (just check his U21 euro final) but still did never make it to an European giant and still during a time when number 10s had a place.
Nevertheless i think you're greatly overrating this guy.
