Novak Djokovic’s father Srdjan has come to his son’s defence in the face of his irresponsible act of organising a tournament during a virus pandemic blaming another tennis player Grigor Dimitrov for spreading the coronavirus at a series of exhibition matches hosted by the world number one Tennis player.

Djokovic, who alongside his wife have tested positive for the virus apologized online for organizing the Adria Tour events, which brought together professional players from various countries to play matches in Serbia and Croatia.

However, speaking on RTL’s Croatian TV network, Srdjan tried to shift the blame for the fiasco on to Bulgarian, Grigor Dimitrov, the first of three other players to test positive for coronavirus in Croatia, where the two-week tour was abandoned minutes before the final on Sunday.

“How did the infection come about?” Djokovic Sr said “Probably because Dimitrov arrived sick, from who knows where. He was not tested in Zadar, but somewhere else. I don’t think that’s right. He brought great harm to you in Croatia, and to us as a family, and to Serbia.”

The Bulgarian’s agent, Georgi Stoimenov, fired back: “Grigor landed directly in Belgrade after three months of complete isolation. Neither in Belgrade [the first stop] nor later in Zadar was he offered or required to test for coronavirus. The event organisers are the ones responsible.”

The coronavirus outbreak led to the suspension of the ATP and WTA tours in March. Plans were announced last week for the sport’s sanctioned events to return in August.

The US Open is scheduled to begin Aug. 31 without spectators.
