Serena and Azarenka have played some of the best matches in the last few years, including a thrilling three-setter in the quarterfinals of the 2015 Wimbledon Championships. Their most recent encounter came last spring, where Azarenka got the upper hand to win the first leg of her Sunshine Double at the BNP Paribas Open.
The Belarusian remains optimistic of a comeback, writing on social media that she hopes to extend her rivalry with the World No.1 on the court in the future.
Azarenka has undoubtedly remained plugged into the sport even from afar, congratulating Serena on her seventh Australian Open title on Twitter not long after the final:
Miss Serena @serenawilliams 23 quite a magic number! Bravo!!! Congrats to Venus as well and your family and your team!
