Novak Djokovic congratulates Australian Open winners after deportation denied him a shot at being first to 21 major titles

Novak Djokovic has congratulated the two Australian Open singles winners, Ash Barty and Rafael Nadal, after being denied the chance to compete for the title.

Nadal's gritty, five-set victory over Daniil Medvedev earned him a record 21st major title, overtaking both Djokovic and Roger Federer who have both won 20 each.

«Congratulations to [Rafael Nadal] for 21st [grand slams],» Djokovic posted on his social media accounts.

«Amazing achievement. Always impressive fighting spirit that prevailed another time.»

The Serbian also had some kind words for runner-up Medvedev, who he beat in last year's Australian Open men's singles final.

"[Medvedev] gave it his all out there and played with the passion and determination we have come to expect from him," Djokovic said.

«You put up one hell of a fight today and I know you will have more grand slam wins in your future.»

Djokovic also acknowledged Ash Barty, who also made history by becoming the first Australian woman in more than 40 years to win an Australian Open women's singles title.

«Congratulations to [Ash Barty] for an amazing performance in front of her home crowd and to Danielle Collins for an incredible tournament,» Djokovic said.

Djokovic was deported on the eve of the Australian Open after his visa was cancelled and his appeals against that decision were dismissed.

The men's world number one remains at risk of missing the French Open, too, with stricter vaccination rules for entering sporting events on French soil coming into effect from February 15. Players are due to hit the Roland Garros courts on May 22.
