Lorenzo Musetti just set the stage for a spicy Aussie Open quarterfinal by calling out the 10-time champ, Novak Djokovic.

Musetti’s 1-9 record vs Djokovic isn’t great, but you’ve got to love his belief. Can youth and hunger topple experience and Grand Slam pedigree? #Sports #Tennis #AustralianOpen
