This year’s contest at SW19 begins on Monday with Williams and Federer looking to add to their Grand Slam haul.
American Serena Williams has 23 major titles, including seven titles in south-west London.
Current men’s world No 1 Federer has tasted victory eight times at Wimbledon and has 20 Grand Slam trophies in his cabinet.
Federer won his first Wimbledon title in 2003, as Williams lifted the trophy on Centre Court for the second time.
It meant they shared the Champions Dinner for the first time.
And now Williams has bragged about the continued success for the pair over the past decade and a half.
She tweeted: “6 days until #Wimbledon
“15 years ago a boy from Switzerland and a girl from the US, both 21, shared the stage at Wimbledon for the first time.. and it wouldn’t be the last.”
Williams won Wimbledon in 2015 and 2016 before missing last year’s tournament as she was pregnant.
Indeed, Williams has played just three tournaments in the past 12 months and doubts remain over whether she will be seeded for this year’s tournament.
The 36-year-old is currently 183rd in the rankings but has called for players returning from pregnancy to have protected seedings.
The decision on whether she will be seeded will be announced at 10am UK time on Wednesday.
Roger Federer won at SW19 last season. having missed the French Open, and the Swiss legend again skipped Roland Garros this year.
