But unlike last year when he arrived at Wimbledon ranked outside the top 20 after one of the most difficult periods of his career, only to silence the doubters to win a fourth title, the 32-year-old looks at the peak of his powers.

One more title here would take him level with the five of Swedish great Bjorn Borg and third on the all-time list for men's champions in the modern era.

It would also leave the Serb four behind Federer's men's record total of 20 grand slams.

It's just awesome to see a dynasty, and then there's another part that says, hey, let's get some other people in the mix here

Federer, seeded two on the 20th anniversary of his first main-draw appearance, is chasing his ninth title and looked razor-sharp last week when he warmed up by winning the Halle grasscourt title for a 10th time.

Then there is the 33-year-old Nadal.

He last triumphed at Wimbledon in 2010, two years after his epic final against Federer, but since then he has endured some bitter setbacks on the lawns - suffering early losses to Steve Darcis, Nick Kyrgios, Lukas Rosol and Dustin Brown before rebounding last year to reach the semis.

After taking a 12th French Open title the Mallorcan seems highly motivated, and physically strong, as he targets a third French Open/Wimbledon double - a feat only Borg has achieved.

Fuelled by desire and unencumbered by the pressure to prove themselves that weighs on the likes of seventh seed Tsitsipas and sixth seed Alexander Zverev, it is hard to see the trophy not in the hands of one of the big three on July 14.

After all, they have won the past 10 grand slams on offer and only Andy Murray (twice) has managed to keep their hands off it since Lleyton Hewitt won in 2002.

"It's just awesome to see a dynasty, and then there's another part that says, hey, let's get some other people in the mix here," three-time Wimbledon winner John McEnroe said.

"To me we have the three greatest players that have ever lived, playing at the same time.

"They're extremely hungry, which is an amazing quality at that age."

Tsitsipas, with his aggressive all-court game, looks the most likely contender to shake things up while 18-year-old Canadian Felix Auger-Aliassime, a semi-finalist at Queen's Club, has jumped the queue after a stunning rise from outside the top 100 at the start of the year.

"Tsitsipas is going to be a great champion and player. He's got everything that you could hope for," McEnroe said. "I think Felix, to me, he's going to be No.1."

Throw another Canadian, 20-year-old Denis Shapovalov, and even the mercurial magic of Kyrgios into the mix, along with old Swiss warrior Stan Wawrinka, Austrian stylist Thiem and a gaggle of powerful Russians led by Karen Khachanov and an absorbing chapter of Wimbledon awaits.

The ending may be a familiar one, though.
