Novak Djokovic won his 20th Grand Slam title on Sunday after beating Italy's Matteo Berrettini in four sets at Wimbledon - the Serbian's third straight triumph at the All England Club and sixth overall.

With his 20th career major title, the World No. 1 is now tied for the all-time men's Grand Slam record with his "Big Three" rivals: Roger Federer and Rafael Nadal.

During the presentation ceremony, Djokovic said equaling the men's record "means none of us three will stop," adding, "I have to pay great tribute to Rafa and Roger. They are legends of our sport and they are the two most important players that I ever faced in my career. They are the reason that I'm where I am today."

After losing a close first set in a tiebreak and contending with a crowd that kept chanting the Italian underdog's name, Djokovic handily won the next three sets.

Having also won the Australian and French Open titles this year, Djokovic only needs to win the U.S. Open to become the first man since Rod Laver in 1969 to complete the calendar slam.

The 34-year-old also completed the third leg towards achieving the Golden Slam, which is winning all four majors as well as the gold medal at the Summer Olympics in the same year, a feat no man has ever accomplished.
