Roger Federer crashes out of Australian Open in four-set loss to Stefanos Tsitsipas

The Swiss tennis champion bowed out of 2019 Australian Open with a shock four-set loss after a stunning display from the 20-year-old Stefanos Tsitsipas.

Federer's chances of winning a third consecutive Australian Open title were ended as Tsitsipas, 20, came of age on Rod Laver Arena.

The Greek, who was not born when Federer made his tennis debut, has rapidly established himself as one of the most promising up-and-coming talents in the sport and backed it up magnificently with a 6-7 (11) 7-6 (3) 7-5 7-6 (5) victory to advance to a first slam quarter-final.

Since a semi-final defeat by Novak Djokovic in 2016, Federer had not lost a match at Melbourne Park but his often-brilliant forehand was awkward, especially at the big moments, and he failed to take four set points in the second set which literally might have changed the outcome.

For the first time all evening, Tsitsipas put on an overwhelmed face as he stepped out for the on-court interview, saying: "I'm the happiest man on earth right now. I cannot describe it.”

"From the very beginning it was very important to keep that mindset, to believe in yourself, believe in your capabilities.”

"Roger is a legend of the sport, so much respect for him. He showed such good tennis over the years. I've been idolising him since the age of six.”

"It was a dream come true just being on Rod Laver facing him. Winning at the end, I cannot describe it."

"I had an aggressive mindset from the start, stayed in the moment, got first serves in and tried to press. I didn't lose my patience and that was the key.”

"I showed fighting spirit and had most of the crowd supporting me. I haven't seen such a large crowd all my life. The atmosphere, the vibes and the energy shown to Roger and me today was indescribable."
