This weekend saw the Laver Cup debut in Prague.
The tournament, which took place between Friday and Sunday, saw a selected European team face a world side, and it was the first time the competition took to the courts.
Team Europe included some big names in Rafael Nadal and Roger Federer, whilst the opposition had the likes of Sam Querrey and Nick Kyrgios on their books.
It was the Europeans, led by Swede Bjorn Borg, who claimed the victory on Sunday, after beating John McEnroe’s side 15-9.
The victory came after world number two Federer beat Australian Kyrgios, despite the match seemingly heading for a deciding doubles.
Federer came out on top 4-6, 7-6, (8-6), 11-9 and claimed the first ever Laver Cup title for Team Europe.
However, as the Swiss celebrated the victory, it all got a bit too much for his opposite number, who broke down in tears.
Kyrgios, who had the chance to take the tie to a decider, claimed the tears were for his team who he felt he let down
"It was tough," the world number 20 said after the defeat via Metro.
"When I’m playing for myself, sometimes I don’t put the greatest effort in when I play on my own. When I play with these guys and I’m playing for something as a team, I’m not just playing for myself out there.
"I’m playing for the whole team. It’s the same in Davis Cup. I’m playing for the country, playing for the guys on the bench. I know that every single one of these guys up here has put effort into this week, whether that’s practice, supporting other guys.
"You know, Johnny Mac supporting us, P-Mac helping us with everything. We all bought in as a team. That’s why it hurt. I gave everything I had. I came short, and I knew that we were going to be favourites going to the doubles. That was in the back of my mind.

"Yeah, it just hurt because I knew I didn’t want to let these guys down. I wanted to come through but I didn’t. Yeah, that’s why I got a bit emotional out there."
