Italian, Lorenzo Musetti, says he thinks he is still dreaming, moments after beating Novak Djokovic in the third round of the Monte Carlo Masters.

The 21-year-old Italian beat the 22 time Grand Slam champion 4-6 7-5, even though Djokovic took a 6-4 win in the first set.

The World No 1 also surrendered a 4-2 lead to lose a rain-interrupted match, in which he dropped serve eight times.

With the score tied in sets at 1-1 and a Djokovic leading in the third game of the decider, wet weather forced the players off t weather forced the players off with the score at 1-1 in sets, and Djokovic leading 40-30 in the third game of the decider. When the players returned, the match stayed on serve until the seventh game, when Musetti secured the decisive break.

Djokovic subsequently saved three match points but Musetti seemed destined for an historic victory.

"I am struggling not to cry because it is a really emotional win because it was a really long match - 3hours match and also suspended by rain," Musetti said on the court in his post-match interview. "It was not easy conditions since the beginning because it was a little bit windy and cold - not like we used to play in the last days.

"I'm really proud of myself, I can see [the score] on the screen. I am struggling to cry because I think it's still a dream for me."

After his Djokovic exploits, Musetti will take on countryman, Jannik Sinner, who fought back to beat Poland’s Hubert Hurkacz 3-6, 7-6 (6), 6-1.
