The first round of the Australian Open will feature a rematch of last year's most impressive Grand Slam upset. Coco Gauff, a 15-year-old Tennis star and the tournament's youngest female competitor, will go up against Venus Williams.

The last time these two faced off was in the first round at Wimbledon, where Gauff's 6-4, 6-4 upset over Williams gave the teenager her first-ever victory at a major. The surprising defeat came as Venus Williams was supposed to be at her best at Wimbledon and the place where she had won five of her seven major titles in Tennis.  

That summer, Coco Gauff went onto become the youngest player to reach the round of 16 at Wimbledon since Martina Hingis in 1996.

Providing they make it to the third round of the Australian Open, the winner of the Coco Gauff v Venus Williams could be facing the one and only Naomi Osaka - the winner of last years Australian Open.

Whoever makes it out of this match could also be facing Serena Williams, who has been working extremely hard to obtain her 24th Grand Slam title since becoming a mother to Alexis Olympia, in the quarterfinals.

The first round of the tournament begins on Jan. 19 in Melbourne, Australia.
