Please correct me if I am wrong, but I believe there have been a very limited number of countries with players ranked #1 and #2 simultaneously.
Belgium (Kim & Justine)
Serbia (Ana & Jelena)
Other countries to have come close (to have a player ranked in #1 around
(not necessarily simultaneously) the time another player was ranked top 3)...
Russia (Maria & Svetlana & Dinara)
Spain (Arantxa & Conchita)
Germany (Steffi & Anke)
Other countries worth mentioning...
Australia (Mandlikova & Turnbull)
France (Mauresmo, Pierce, Tauziat)
Czechoslovakia [Czech Republic] (Mandlikova & Sukova)
Great Britain (Wade & Barker)
As I am not a rankings expert, if another country has come close, and you'd like it mentioned here, let me know!
So who is next?
NOT including the 3 countries that have got there in the past, what country do you think could be next?
Countries that currently seem kind of close (or at least not so close) include...
France (Cornet, Bartoli, Mauresmo)
Slovak Republic (Hantuchova, Cibulkova)
China (Zheng & Li)
Italy (Pennetta & Schiavone)
other countries that have some distant potential...
Great Britain, Australia, Spain, Poland (Radwanska sistahs!), Japan, Ukraine (Bondarenko sistahs!), Germany, Belarus, Austria
