Watch: Novak Djokovic crushes racket with leg, argues with umpire & gets loudly booed

Novak Djokovic got extremely frustrated during his Monte Carlo Masters match against Lorenzo Musetti. After one Musetti ball appeared to be well out in the second set, Djokovic argued that the line umpire and then the chair umpire missed the mark.

While Djokovic was pleading his case to the chair umpire, the Monte Carlo crowd started booing the Serb.

Djokovic-Musetti played a thriller second set
Djokovic won the first set against Musetti with a 6-4 score and then the things got interesting. After losing the first set, Musetti started the second set with a break. Djokovic broke back Musetti in the second game but the Italian again broke the Serb in the third game.

Down by a break in the second set, Djokovic responded by claiming back-to-back breaks in the fourth and sixth games to overturn the deficit and take a 4-2 lead. After being up by a break twice early in the second set, Musetti found himself down by a break.

But just when it seemed Djokovic was able to break Musetti mentally, the Italian responded by earning back-to-back breaks in the seventh and ninth games to overturn a 4-2 deficit into a 5-4 lead. Serving for the second set in the 10th game, Musetti failed to close out the set as Djokovic broke back to tie the second set to five games apiece.
