its not easy maybe you can go with him to Canada summer academy and if he is good you may get an offer for him to come to zagreb but it is hard he needs to be excellent.
A tip. Buy your son a tennis ball and tell him to dominate as much as possible make a goao of 100 consecutive touches in 1 week that will improve his eye coordination and will increase his touch immensely and will teach him to do light touches for better ball control while dribbling.
