Novak Djokovic is pushing for changes in the Serbian Tennis federation.

Serbia's 3-2 triumph in the Davis Cup final earlier this month was the proudest moment in the country's sporting history but there has since been clashes between the Djokovic family and current tennis federation president Slobodan Zivojinovic.

“I'm really sorry that the situation is almost out of control but changes are inevitable," Djokovic told his website while holidaying in Dubai.

"The Tennis Association needs new people in order to finally build a national tennis centre and provide better conditions for young talents to progress. I have to say my father has no intention of taking any position in the TSS, but to present to all clubs the functioning of the concept he represents.”

"He does it very successfully and we fully support him because prosperity and well-being are guaranteed with the new management."

Djokovic's father has called for Zivojinovic to step down, a claim backed by the current Davis Cup captain and the rest of the squad but Zivojinovic has insisted he will run for another four-year term.
