apparently collarini is from argentina but moved to america
He is. His parents are argentinean and he lived in argentina his whole life. But he was born in New York because his father worked there at that moment.
In fact he and Velotti have been the Argentina singles and doubles players in Argentina juniors teams their whole careers until now.
But the USTA realized that all the millions they spend anually on tennis development weren't "producing" enough, so they cut to the chase and "bought" him. Nice!
Obviously for Andrea was a no brainer. This kid is gonna be a very good player, I hope the USTA is sued properly for his formation rights.
Congrats to both Agustin and Andrea for this great result.
PS for argentines:, beware of attacking Andrea, it's very easy being patriotic with other people future and money.
