Eighteen years after winning his first title in Milan by beating long-forgotten Frenchman Julien Boutter, Federer on Saturday became just the second man after Jimmy Connors to win 100 career singles crowns.
Among that collection are 20 Grand Slams, 27 Masters and six World Tour Finals.
Off court, he is the father of two sets of twins, Myla Rose and Charlene Riva and Leo and Lenny with wife Mirka, a former player he met at the 2000 Olympics in Sydney.
But his career and life wasn’t always so settled.
As a talented young player, Federer’s hair-trigger temper once threatened to stunt his undoubted ability. Place Live Bet on NaijaBet 24/7
“I had a tough time getting my act together out on court, trying to behave properly. For me that was a big deal,” he once admitted.
Federer announced himself in the big time when he famously defeated childhood hero Pete Sampras at Wimbledon in 2001.
It took a personal tragedy for Federer to press the reset button.
Just when he turned 21, his coach and close friend from his formative years Peter Carter was killed in a car crash in South Africa.
From that point on, the multi-lingual Federer committed himself to winning in style, with grace and not engulfed by his inner demons.
Born on August 8, 1981 in Basle, to Swiss father Robert and South African mother Lynette, Federer started playing tennis at eight.
That extended rest, to recover from a knee injury, led to his 2017 renaissance with a refreshed Federer winning his 18th major at the Australian Open.
A record eighth Wimbledon in 2017 was his 19th Slam title with his 20th and most recent coming back in Melbourne last year.
Federer was also a Davis Cup winner in 2014 and a 2008 Olympic doubles gold medallist with close friend Stanislas Wawrinka.
With his 38th birthday in August this year, Federer has always insisted he has never set a date for retiring.
“It’s just discussions I always have with my wife about the family, about my kids, is everybody happy on tour, are we happy to pack up and go on tour for five, six, seven weeks. Are we willing to do that?,” he said after winning Wimbledon in 2017.
“For the time being, it seems like absolutely no problem, which is wonderful.”
