Roger Federer will go down as possibly the greatest tennis player of all time.
The 37-year-old has shown throughout his long and illustrious career that he can remain playing at the highest level, and during said career, he has won a staggering 20 Grand Slams in the process.
He also stirs up some banter and humour as well, further stating his case as one of the most liked players in the game.
In the Hopman Cup final in a mixed doubles match in Sydney Australia, the Swiss man, alongside compatriot Belinda Bencic, went up against Greek pair Stefanos Tsitsipas and Maria Sakkari.
It was with Maria Sakkari that Federer had a hilarious exchange and just highlighted the parts of his character that makes him such an enjoyable player.
The young female star Sakkari, before one of Federer's serves, jokingly yells out the question "left or right?" refering to where on either side of her would Federer serve the ball.
Playing along, Federer responded back for the arena to hear and said, "I don't know, I already told her (Bencic) so I'm not gonna change.:
The entire exchange between Switzerland's Federer and Greece's Sakkari can be seen here.
What followed was an uproar of laughter in the arena and a funny atmosphere was instilled even during a cup final.
The 37-year-old Swiss superstar surprisingly ended up losing out to the Greek couple and handed the very young stars a flattering win in their early careers that they will truly never forget.
As if beating Federer is not flattering enough for Tsitsipas, he currently sits 15th in the world tennis rankings, sitting 12 spots behind Federer, and wins like this against one of the best players of all time will do wonders for the 20-year-old's quest to being ranked the number one player in the world.
