It marks a sixth Masters title for the 21-year-old Spaniard, a four-time Grand Slam winner, and his most prestigious title since winning Wimbledon last year.

"I'm just really happy to have won Monte Carlo for the first time," said Alcaraz who lost in his first match on his only previous appearance at the tournament in 2022.

"It's been a really difficult week with a lot of difficult situations.

"I'm really proud of my myself how I've dealt with everything. It's been a really difficult month for me on the court and outside.

"Coming here and seeing how the whole hard work has paid off, I'm really happy."

Alcaraz, who will move up a place in the rankings and displace Alexander Zverev at No 2, had to come from behind to beat the Italian who had already taken down two Top 10 players, Stefanos Tsitsipas and Alex de Minaur, on his way to his first Masters 1000 final.

Musetti dropped his opening service but then fought his way back into the first set as Alcaraz appeared at odds with his game.

The Spaniard bounced back, however, lifting his game as he galloped through the second set 6-1.
