I suppose it's isn't bad for a country to have 4 players in the top 100 at the same time so I hope it will happen
Apart from Medvedev who was Russian and Davydenko who is Ukrainian but plays for Russia they were a blank place on the ATP map. And now this possibility... I just found it curious
Serbia also appeared out of nowhere with Djoko, Troicki, Tipsa and Bozo...
but thanks for your thoughts.
