WATCH 'What's he doing in there?' Moment Andy Murray loses it over Tsitsipas toilet break

Andy Murray got into a verbal clash with the US Open supervisor Gerry Armstrong as he complained of Stefanos Tsisipas’ long toilet breaks. The Scottish champion challenged the repeated interruptions, claiming the length of the break was difficult to justify due to the toilets being very close to the court. Murray’s complaints were caught on video as he argued with the supervisor.

Murray went on to suggest Tsisipas’ toilet breaks were an attempt to shift momentum from the match.

The world’s number 3 later said he lost “respect” for his Greek opponent, telling the press after his defeat: “It’s not so much leaving the court. It’s the amount of time.

“I spoke to my team before the match about it and said [we should] prepare for it if things were not going his way.

The issue is that you cannot stop the way that that affects you physically. When you’re playing a brutal match like that, [and you are] stopping for seven [or] eight minutes, you do cool down.”

“The match went on for another two-and-a-bit hour after that or something. He was fine, moving great I thought.

“It’s just disappointing because I feel it influenced the outcome of the match.

“I’m not saying I necessarily win that match, for sure, but it had influence on what was happening after those breaks.

“I rate him a lot. I think he’s a brilliant player. I think he’s great for the game. But I have zero time for that stuff at all, and I lost respect for him.”
