Luca's fundamentals are amazing for 14. Who has worked with him? He may be natural; however, I doubt very much he learned those fundamentals on his own. That is a strong combination of fundamentals & natural talent.
Here is an interesting article about his strengths and weaknesses:

It amazes me that he can take a very long full backstorke given his size. It's interesting watching his shoulder span out backward to get the cue back so far.
Nice thread! Thanks!
