Novak Djokovic has called for tennis to fully embrace technology and use Hawkeye in every tournament.
The French Open, as with most clay court tournaments, are not using Hawkeye in favour of allowing chair umpires to examine the mark on the court left by the ball instead.
That has seen a number of controversial calls made, though, and Djokovic wants tennis to re-evaluate its need for line-judges in the modern era.
“With all my respect for the tradition and the culture we have in this sport, when it comes to people present on the court during a match, including line [judges], I really don’t see a reason why every single tournament in this world, in this technological advanced era, would not have what we had during the Cincinnati/New York tournaments,” Djokovic said.
“The technology is so advanced right now, there is absolutely no reason why you should keep line umpires on the court. That’s my opinion.
“Of course, I understand technology is expensive, so it’s an economic issue and a question mark.
“But I feel like we are all moving towards that, and sooner or later there is no reason to keep line umpires.
“Yes, ball kids, of course, ball person, yes, but line umpires, I don’t see why anymore, to be honest.”
His opinion is also shared by US Open champion Dominic Thiem, despite him actually benefiting from a mistake this week.
"In my match there was a mistake – in my favour actually,” Thiem said. “Casper [Ruud] showed me the mark on his phone after the match.”
"I hope that next year, we will have it in every clay-court tournament.”
