'Irresponsible' - The reaction to Novak Djokovic testing positive for Covid-19

Djokovic was criticised for hosting the tournament amid a pandemic after Grigor Dimitrov, Borna Coric and Viktor Troicki also returned positive tests after playing in the tournament that was held in Serbia and Croatia.

Here are some of reactions from the tennis world to the Serb's positive test...

Patrick McEnroe, former doubles champion and commentator said in a video:

"When I sent out a tweet a couple weeks ago about that event in Serbia I said yeah it looks like a normal tennis event to me. I'm not sure everyone got my point, maybe they are starting to get it now. Nothing's foolproof so don't be foolish. That's my message."

Over the past two days, organisers have also been criticised for allowing stands to be packed with fans during the opening leg in Belgrade.

With no social distancing rules in place in Serbia, players hugged at the net, played basketball, posed for pictures, attended press conferences and were out dancing together.

He said: "I don't think he should be having a players' party and dancing all over each other, Players have tested positive. He should feel some responsibility in his event and how it's transpired, really.

"It's very unfortunate that Grigor has it and Coric has it but you strip it back, is it a surprise? I think that's the question we should all ask."
