Novak Djokovic and French Open referee blasted by Serena Williams' ex-coach - 'So unfair'

' former coach wasn't happy with and Mackenzie McDonald after they managed to get the roof closed during their first-round clash in Paris. when he went up to the umpire and pointed out that the blustery conditions were making it difficult to continue.

Supervisor Ali Nili later came out to speak to the players, and there was another delay a few games later when McDonald started asking when the roof would finally be pulled across Court Philippe-Chatrier. It was eventually shut in the middle of a game, but Rennae Stubbs blasted the "unfair" decision.

Djokovic was the first one to complain about the weather on the main show court at the French Open. He pointed out that they had a roof, so they should use it.

It was windy on Tuesday afternoon, and the Serb, who wears contact lenses, said stuff was flying in his eyes. It didn't help that it had also started to drizzle, and McDonald later seemed keen to play in indoor conditions too.

After discussions with the umpire and supervisor, the players' wish was granted towards the end of the first set. However, play continued unaffected on the smaller outdoor courts at Stade Roland-Garros.

And top tennis coach Stubbs wasn't happy to see those on Chatrier get preferential treatment with the roof.

"I'll say it again. This is SO UNFAIR to every other player playing out there on the outside courts," she tweeted.

"Nonsense from the referee. He should say, too bad, u have to play no one else is stopping outside. Yes the weather sucks, the wind sucks but i can tell u, this is unfair for others."

Replying to a fan who pointed out that it had also been raining, the retired Aussie tennis star added: "Yes. It happens ALL THE TIME on clay.

"If they're playing outside with NO ROOF available they should be playing on the roof courts with the roof open! Now if they're stop playing outside then close the roof."

Djokovic managed to come through his opening round with ease after the early roof debacle, beating McDonald 6-3 6-3 6-3.

It was his first match on Court Philippe-Chatrier since he won a long-awaited Olympic gold medal last summer, beating Carlos Alcaraz in the final.

But the world No. 6 has , as he was part of Rafael Nadal's emotional tribute ceremony on Sunday, with Roger Federer and Andy Murray also coming out.

"It was a beautiful moment, really one of the nicest moments I have experienced on this court," he said of the presentation.

"Really, walking into the court with Federer and Murray alongside and being there for Nadal and experiencing all the glory of the celebrations of his career. We were all happy for him because he absolutely deserved it."
