Recently a few players joined big clubs? It's possible that I fully missed that of course, but which players are you talking about and what clubs are they playing for today? I am not aware of any player from Uzbekistan playing for a big club. Very few have made it to the European top leagues as far as I know and if they made it there, they didn't play for the best clubs. I am all ear to learn from you where those players are now at.
Well, just last January Abdukodir Khusanov joined Manchester City from Lens for over 40 million euros, that's a lot of money. In Italy there is Eldor Shomurodov, who player for Genoa and now he is with Roma. These two for sure are the most famous ones; many others still play in Uzbekistan (Pakhtakor especially) and there is someone in Turkey, Russia, and the Middle East.
I remember that in the late '90s / first '00 they the most famous players were Geynrikh and, especially, Shatskikh, which was a legend. My team, Juventus, at that time had Zeytulayev but he didn't really play. Probably the majority of players are not very famous but this team is better than ever, their football movement has grown a lot.
Ok missed that and thank you for clarification. Now two players playing for Manchester City and Roma is definitely fostering progress within the Uzbekistan team as a whole. While two players can't turn them into a World Cup title contender, you could see from Georgia how much impact some top players can have on the team. Mamardaschvili and Mikautadze improved Georgia's game so much that you can see two players can do something, but there are limits.
In order for a national team to develop a highly competitive squad, it takes many years, if not more than a decade and even then it is close to impossible to being a nation that is not that popular for football to a level that it can compete with the best national teams in the world. In one games maybe yes, but not in a whole competition from the beginning till the end.
Greece has once done the impossible, but I think it hasn't happened again that a team like that won something big.
