I've said for a while that these central Asian countries may have a lot of untapped potential if they improve the infrastructure for football.
My parents came from the Soviet Union and we have friends from ex soviet countries like Uzbekistan, Kazakhstan, Kyrgyzstan etc. And one thing I know is a lot of people from these places are great athletes. You only have to look how good their boxers are, because that's one sport they actually put time into developing. If they do that with football from grass roots level, then don't be surprised to see some more real talent emerge from that part of the world in the future. Especially now the Uzbeks qualified for the world cup, and they're producing a player like Khusanov, it may just be a little glimpse into that part of the world starting to produce talent.
Interesting part of the world. Their athletes always have some ridiculous power or speed or agility.
