By Zoran Milosavljevic NOVI SAD, Serbia, Jan 30 (Reuters) – Novak Djokovic has earned his right to miss Serbia’s Davis Cup first round tie against a full-strength Switzerland, team coach Bogdan Obradovic said on Thursday. With world number two Djokovic resting in Serbia’s skiing resort of Mount Kopaonik, the Swiss will be strong favourites to advance after former world number one Roger Federer joined Australian Open winner Stanislas Wawrinka as a surprise late inclusion. “Novak is exhausted and made it clear he needs to recuperate for what will be a gruelling season on the ATP Tour,” Obradovic told a news conference after the draw pitted Federer against world number 268 Ilija Bozoljac in Friday’s opening singles rubber.
