Roger Federer and Marin Cilic were involved in an unusual row with the umpire over the pace of play and taking time to get towels during their French Open second-round clash.
The 20-time Grand Slam champion had a lengthy exchange with the umpire when 3-1 down in the second set after Cilic had apparently complained over the time being taken to get towels at the back of the court between points.
After the long discussion with the official at the net in French, which at times got pretty heated, Federer then questioned Cilic himself about the situation.

Cilic replied: "You were not playing too slow but, on a few occasions, I was waiting for you!"
Federer shot back: "I understand. But I am going from one corner to the next, trying to get my towel.
"I'm not even doing it on purpose!"
Cilic replied again: "That's fine but, I mean, you're playing like this all the time..."

At that point, Federer turned and walked back to the baseline, clearly not overly happy with the exchange.

Eurosport's Chris Bradnam commented: "Well, you will have your own opinions at home. Has Cilic got a point?
"As Federer goes to get the towel, he is ready to play, that's a good picture of what we are talking about here. Cilic probably has a point."
Rafael Nadal, Novak Djokovic and Federer have all found themselves in the same part of the men's draw in what is an intriguing prospect.
The draw looks particularly exciting for Stefanos Tsitsipas, Daniil Medvedev and Alexander Zverev with the trio not having to face any of the 'Big Three' until the final at least.
Djokovic could take on Nadal in the semi-finals in Paris in what would be a repeat from last year's final in the postponed autumnal edition.
The three most successful players in the history of the men's game have won 17 of the last 20 Grand Slam titles between them.
