I read it on Serbian's newspapers, and I will try to translate it.
Novak Djokovic now have a harder task to defend the trophy won last year in Belgrade. Spaniard Tommy Robredo, one from pleiad who grown up players on Spanish clay, confirmed to he will play on Serbia Open 2010, because he got WC from organizers.
Organizers still do not gave 1 remaining WC.
In Serbia Open there are only 2 Wild Cards.
First WC goes to Robredo.
