The Davis Cup could be about to undergo a major format change, according to International Tennis Federation president David Haggerty.
With Great Britain's historic victory over Belgium in the 2015 final still fresh in the memory, Haggerty has revealed a proposal that would see both semifinals and final played over a single week each November at a neutral venue.
As it stands, the annual team competition features a 16-nation World Group with each round played on specified weekends throughout the year, with one team hosting the other. Britain's win over Belgium was at Ghent's Flanders Expo Arena.
"What would be very interesting for me is a final four concept," Haggerty told ITFWorld magazine, according to Reuters.
"We would be able to plan in advance where that is. We could have the semifinals in the first three days, a day of rest and then three days for the final."
Another idea championed by Haggerty is to hand the reigning champions a bye in the opening round of the following year's competition. Switzerland, winners in 2014, were eliminated by eventual runners-up Belgium last year, with star names Roger Federer and Stan Wawrinka opting out of the tie.
"The players I have talked to have been very positive about that idea and I think it would cause them to play a little more than they do right now," Haggerty added.
"[The Davis Cup] is a great property, but I want to polish it a little bit. We've got to make sure what we do resonates with the fans and spectators."
Haggerty will invite the captains of the 16 World Group teams, including Great Britain's Leon Smith, to discuss the plans at the Australian Open, which begins on January 18.
Meanwhile, Great Britain have been handed a favourable draw in the Fed Cup, the ladies' equivalent of the Davis Cup.
Judy Murray's six-strong squad of Johanna Konta, Heather Watson, Laura Robson, Katie Swan, Jocelyn Rae and Anna Smith will take on Georgia and South Africa in their pool in the Europe/Africa Zone Group I round-robin tournament in Israel starting on February 3.
Neither Georgia nor South Africa has a player ranked in the top 200, so Britain will be confident of winning the group.
