Rome, June 20 -- World number one Jannik Sinner has swapped his tennis racquet for a microphone to release a duet with fellow Italian and tenor Andrea Bocelli.

The pair have released a song called Polvere e Gloria, which means Dust and Glory, and includes Sinner, 23, repeating parts of his winning and losing speeches.

"I am very happy and honoured to be part of this project with Andrea, who for 30 years has been a unique and extraordinary voice, a flag for our country in the rest of the world," said Sinner, who is the first Italian to top the men's rankings.

"I could never have imagined hearing my voice in one of his songs. It's extremely moving."

The song has both Italian and English lyrics and its accompanying video features scenes...
