With 2020 wrapping up after one of the craziest seasons in tennis history, it's only natural for players and fans to look towards next year for a fresh start. A number of "NextGen" or 21-and-under players stalled out this season, but that doesn't mean they aren't aiming for big things in 2021.

Some potential breakout stars for next year include Jannik Sinner, who earned his first ATP title to end 2020, Brandon Nakashima, who won his first ATP Challenger title, and, of course, Coco Gauff, who seems to play her best on the biggest stages. 

With so much potential and fresh talent coming into the 2021 season, we want to know which male or female player you think has the best chance to become the biggest breakout star.
