Federer won the Davis Cup back in 2014 but neither he nor great rival Nadal are regular competitors in the format.
But plans are afoot to transform the team tournament into a World Cup of Tennis Finals, which would be held in one location over seven days at the end of each season.
And Becker reckons that the shorter format would allow the best players in the world to be part of it.
“Davis Cup is the oldest team competition we have in tennis, the most prestigious and the most important,” said Laureus ambassador Becker, who was speaking ahead of the Laureus 2018 World Sports Awards, which both celebrate sporting excellence and harness the power to sport to promote change.
“But we all agree that the Davis Cup format needs refurbishment and a few changes and I’m happy that the authorities have realised that. It started, that discussion, a while ago.
“Ultimately it’s about how to get the best players to play with the least amount of time.
“We want to see Federer and Nadal every week, but they can’t play every week.
“We have to choose and make the schedule ideal so you have the best players competing for their country.
“The current format has four ties over a whole year.
“It’s almost impossible to get the best players to play every year.
“So it’s important to reduce the ties and I’m a big fan of a one-week competition where you get the best players, maybe in another country on another surface, to compete in one week and who is the best country.
“I like that idea very much and I think most players like that idea very much.
“It’s important to go with the times and I think the ITF have done with that.”
The plans have major backing, with Barcelona and Spain footballer Gerard Pique heading the funding group who have announced a $3billion partnership with the ITF to pay for the tournament.
Matches would consist of a two singes rubbers and one doubles, each best of three sets, as well as a play-off round to allow eight nations to qualify for the follow year’s finals. The zones below would continue in their current format.
David Haggerty, the ITF president, said: “This is a complete gamechanger for the ITF and for tennis.
“Our vision is to create a major season-ending finale that will be a festival of tennis and entertainment, featuring the world’s greatest players representing their nations to decide the Davis Cup champions.
“This new partnership will not only create a true World Cup of Tennis but will also unlock record levels of new investment for future generations of tennis players and fans around the world.”
