I agree with that point, Turkish clubs have super crazy foreign players like Boskovic, Mihailovic, Kim, Natalia, Maja etc.
But the problem is here Turkish local players are not good enough if to compare with Italian local players IMO. Italian local players can support foreign players much more than Turkish local players. Ofc it also affects their NT, Italy got silver medals in WCH. Turkish league have a lot of strong foreign players, but their local players are not even close to Italian local players. There are a lot of long rallies in Italian league, even if Imoco is another level. Italian locals have a good balance with foreign players that's why they are doing amazing job. Probably for that, today Italian NT can build 2 or 3 or more roster from those players.
