Novak Djokovic lauded Rafael Nadal and Roger Federer as inspirations after he claimed his 20th grand slam title at Wimbledon.

Djokovic overcame Matteo Berrettini 6-7 (4-7) 6-4 6-4 6-3 on Sunday to win for the sixth time at the All England Club, matching Nadal and Federer's haul of slam titles in the process.

The world number one dropped just two sets throughout the tournament and will now head to the US Open looking to complete a calendar Grand Slam.

Asked what it meant to draw level with his two great rivals, Djokovic said: "It means none of us three will stop, that's what it means.

"I have to pay a great tribute to Rafa and Roger, they are legends of our sport, they are the two most important players I ever faced in my career. They are the reason that I'm where I am today, they've helped me realise what I need to do to get stronger mentally, physically, tactically.

"When I broke into the top 10 for the first time I lost for two, three years all of the big matches I played against these guys. Something shifted in 2010, the beginning of 2011 and the last 10 years has been an incredible journey that is not stopping here."

Djokovic, 34, will go to New York looking to overtake his rivals and create history as he looks to become only the second man to win the four majors in the same year.

"I could definitely envisage that happening. I'm hoping, I'm going to definitely give it a shot," he said.

"I'm in great form. Playing my best tennis at grand slams is my highest priority at this stage of my career. Let's keep it going."

Djokovic beat Federer in an all-time classic Wimbledon showdown in 2019, though did not quite find his best form against slam final debutant Berrettini.

"It was more than a battle, I would like to extend congratulations to Matteo," he said.

"I know it's not the best feeling losing in a final. I'm sure there's a great career ahead, I truly believe that. He's got an incredible game, very powerful - true Italian hammer! 

"Winning Wimbledon was always the biggest dream of mine as a kid, I've told this story many times but I have to repeat it to remind myself how special this is and not take it for granted. On the contrary, to enjoy and be aware that this is a huge honour and privilege.

"A seven-year-old boy in Serbia, constructing a Wimbledon trophy from materials I could find and today finding with a sixth Wimbledon [title] it's incredible, amazing."

Berrettini took a front-foot approach and struck an impressive 57 winners, but ultimately his unforced error count of 48-27 to Djokovic's tally – proved costly. Indeed, the Italian lost the match when he sent a weak backhand into the net.

"Unbelievable feelings, maybe too many to handle," Berrettini said.

"For sure he was better than me, he is a great champion. Well done Novak, once again, he is writing the history of this sport so he deserves all the credit.

"I'm really happy for my final, hopefully it's not going to be my last one here, my last one in a grand slam."
