His tearful victory in Paris allowed him to become only the fifth player to complete a career Golden Slam of all four majors and Olympic gold.

The victory also silenced the increasing number of doubters who had written off the Serb as a spent force in a new era where Sinner, 23, and 21-year-old Alcaraz are steadily moving centre stage.

Djokovic, who underwent surgery on his right knee in June, described his Olympic victory as his “biggest sporting success”.

It was also the 99th title of his professional career.

‘Biggest success’

“At the age of 37 and facing a 21-year-old who is probably the best player in the world right now, winning Roland Garros and Wimbledon back-to-back, I can say that this is probably the biggest sporting success I have ever had,” insisted Djokovic.

Sinner arrives at the final Slam of the season having captured the Cincinnati Masters title.The final major of the year comes at a critical time for Djokovic.

This year he was succeeded as Australian Open champion by Sinner who also relieved him of his world number one ranking.

Carlos Alcaraz took his French Open title with the Spanish crowd-pleaser then sweeping Djokovic off court in a one-sided Wimbledon final.

However, Djokovic, returned to the clay courts of Roland Garros to stun Alcaraz in the Olympic final.
