Novak Djokovic's bid for a 100th career title was spoiled by Italian Matteo Arnaldi, who beat the Serb 6-3, 6-4 in the Madrid Open second round on Saturday.
The fourth-seeded Djokovic suffered a second consecutive opening defeat, he also exited in his opener against Alejandro Tabilo in Monte Carlo two weeks ago.
Amazing Arnaldi from start to finish 💪

Arnaldi, ranked 44th in the world, recorded just the second top-five win of his career and scribbled 'OMG' on the camera lens after his landmark victory.
"At the start I was just trying to not s*** in my pants, to be honest," said the 24-year-old Arnaldi.
The athletic Arnaldi squandered a 2-0 lead early in the contest but pounced again in the eighth game, breaking the Djokovic serve. The Italian wrapped up the opening set in 48 minutes.

"He's my idol, he's always been. I was just glad that I could play him because I never played him, I just practised once with him. So playing him on a stage like this was already a victory for me," said Arnaldi, who showcased an entertaining brand of all-court tennis.
"But, you know, he is not at his best right now, so I came on court to try to play my best tennis and win. It happened. So right now, I don't even know what to say."
Elsewhere, Lorenzo Musetti, playing his first match since reaching the biggest final of his career in Monte Carlo, moved past Argentina's Tomas Etcheverry 7-6 (7/3), 6-2 to book a third-round meeting with Stefanos Tsitsipas.
Mesmerising Musetti 🤩

The talented Italian is on the cusp of making his top-10 debut, having entered the tournament at a career-high number 11.
Musetti admitted he is doing his best not to check the ATP live rankings website until he officially joins the top-10 club.
"This week, I don't want to look," said the 23-year-old, who moved up to No 9 in the live rankings on Saturday.
