Novak Djokovic says the Davis Cup knockout phase "has to travel" around the world as he prepares for Serbia's quarter-final against Britain in Spain.
Since a revamp of the men's team event in 2019, the final stages of the tournament have always been played in Spanish cities.
On Thursday Serbia play Britain in Malaga, where the semi-finals and final will be held at the weekend.
"This is a competition that is played globally," Djokovic said.
"It shouldn't stay in one place more than a year."
Eight nations have been competing in the week-long event, but Spain failed to qualify.
