"Coming off from the surgery, being unable to have consistency with results, this was a huge springboard for me, the win at Wimbledon previous year", said Djokovic, who will take a 10-2 career record over Philipp Kohlschreiber into their first-round clash today.
But Federer is quick to praise the influence of Djokovic and Nadal - between them, the trio have won 53 of the last 64 Slams.
Top seed Djokovic, 32, saw his bid to hold all four major titles at the same time derailed by Austria's Dominic Thiem in the French Open semi-finals, yet remains the favourite to win Wimbledon as he looks for a 16th Grand Slam triumph. Federer, promoted to second seed, can win a ninth crown while two-time champion Nadal is seeking to complete a rare back-to-back Roland Garros-Wimbledon double.
Unfortunately for the home crowds, Andy Murray will not be competing in the singles competition this year, although they will get to catch a glimpse of him in the men's doubles, where he will be competing with Frenchman Feliciano Lopez, with whom he won at Queen's last month. She lost to former Roland Garros champion Jelena Ostapenko in the second round at Birmingham, then went out to Tunisia's Ons Jabeur in the third round at Eastbourne. "That's what kind of gave me that push - and also a huge relief".
British men's number one Kyle Edmund, seeded 30th, will play Jaume Munar of Spain in the first round on Monday.
After defeating Kevin Anderson in the Wimbledon final last July, Djokovic beat Juan Martin del Potro in the U.S. Open final in September and Rafael Nadal in the Australian Open final in January. I think it's a system and a structure that keeps on failing us.
"I won here in 2010 after a very, very tough first couple of rounds". "Coming off from the surgery, being unable to have a consistency with the results, this was a huge springboard for me, the win at Wimbledon a year ago".
Greek seventh seed Stefanos Tsitsipas, 20, is expected to lead the charge of the young guns aiming to topple the old guard, while Italian Matteo Berrettini and Canadian youngster Felix-Auger Aliassime could also make their mark.
"I think it's better for me now to be number two here".
Roger Federer has won the Wimbledon men's singles title a total of 8 times and is regarded as the best men's player to ever play on grass.
"There's more attention, there's more of that outside noise". I'm happy the way I've been practicing so far here, I've been playing.
Federer, chasing a 21st major, first played Wimbledon in 1999.
