World No. 1 Novak Djokovic realized a childhood dream on Sunday when he beat Matteo Berrettini in four sets to win his sixth title at Wimbledon and a record-equalling 20th Grand Slam crown.

With his latest triumph at SW19, Djokovic has joined his illustrious peers Roger Federer and Rafael Nadal in an unprecedented three-way tie atop the Grand Slam leaderboard.

It wasn't all plain sailing for Djokovic, who squandered a 5-2 lead in the first set before dropping it in a tiebreak. But normal service soon resumed as the Serb hit back in the second set to draw level.

The 34-year-old then clinched the next two sets to become only the third male player in the Open Era to win six Wimbledon titles and the third in history to win 20 Majors.

The Serb will now look to follow in the footsteps of the great Rod Laver and complete the Calendar Slam by winning the US Open later this year.

In the wake of Djokovic's Wimbledon triumph, congratulatory tweets poured in from the tennis fraternity. Here's a look at a few of them:

Roger Federer was one of the first people to laud the Serb for reaching 20 Majors, a feat previously achieved by the Swiss himself and Rafael Nadal.

Congrats Novak on your 20th major. I'm proud to have the opportunity to play in a special era of tennis champions. Wonderful performance, well done!

Wishes from other players and eminent personalities from the tennis fraternity soon poured in.

Rod Laver, the only male player to win the Calendar Slam, congratulated Djokovic for moving to within one Major of completing the feat.

Congratulations Novak. Amazing achievement, you are on your way to a Grand Slam. Matteo, you played a fantastic tournament and I have no doubt your time will come. https://t.co/bRY6J8B9Lx

American tennis legend Billie Jean King called Djokovic "the best" and lauded him for producing his best tennis under pressure.

Congratulations to @DjokerNole, 6x #Wimbledon champion!

He’s simply the best, and thrives on pressure. The Golden Slam is still in his sights.

Next up: the Olympics. πŸ‘ https://t.co/rOg2h8LEIA

Former British player Greg Rusedski tweeted that there may be no stopping the Serb from achieving the Calendar Golden Slam (Olympic gold and all four Slam titles in the same year):

It’s been awesome to have @Wimbledon back ,with full capacity for the final. @DjokerNole making history with his 20th major & counting. Hard to see anyone stopping him doing the calendar slam and the Olympics. If he does that there is no debate about the GOAT in the men’s game.

Former Wimbledon champion Simona Halep also congratulated Djokovic, tweeting:

Two-time Grand Slam singles champion Mary Pierce called Djokovic's 2021 Wimbledon win "one of the best ever", saying:

Serena Williams' coach Patrick Mouratoglou described Djokovic as "the most complete player" ever.

Novak is the most complete player of all times. That enables him to find the solution to most of the problems on court and this, on every surface. It explains why he is now in the best position to become the GOAT.

Former American tennis player and acclaimed coach Brad Gilbert tweeted that Djokovic is closing in on the Calendar Golden Slam, a feat last achieved by Steffi Graf in 1988.

Former Wimbledon champion and Djokovic's current coach, Goran Ivanisevic, said his charge has probably sealed the GOAT debate in his favour by drawing level with Federer and Nadal for most Grand Slam singles titles:

Goran Ivanisevic believes Novak Djokovic has ended the GOAT debate #Wimbledon https://t.co/J1eiE1V1np

β€” Express Sport (@DExpress_Sport) July 11, 2021
"For me, not because I'm here, before I was member of the team, for me he (Djokovic) was the best," Ivanisevic was quoted as saying by the Express. "I say he's the only guy who can win four in a row in the same year. I don't know. If he wins US Open, I think it's over.
"But Nadal is going to fight. Nadal is going to come to French next year. He wants to win more. But for me Novak is the biggest ever, he's gonna best, he's biggest. I don't even have to debate about that."

Former Serbian doubles specialist Nenad Zimonjic termed Djokovic's win as "impressive", tweeting:
