Barcelona footballer Gerard Pique has insisted the inaugural Davis Cup Finals in Madrid have been an "absolute success", although he did admit some changes would have to be made in future.
The controversial week-long finals were launched by Pique's investment company Kosmos, replacing the old World Group which saw teams play each other in longer ties spread across the year.
"The competition is an absolute success," Pique told broadcasters Movistar on Saturday.
"The most important thing is that it has a soul... The players have reactions that they don't even have in the Grand Slams."
"Things are going to be retouched, obviously. The issue of the schedules must be retouched. But that's what happens to events when the format is changed."
