Roger Federer: Swiss star in row with Gerard Pique - Is the Laver Cup the real reason why?
ROGER FEDERER fired a warning to Gerard Pique about the Davis Cup but his real grudge could be because of the Laver Cup.
As the founder and president of sports and media investment group Kosmos, Pique has been the face of plans to transform the Davis Cup.
The approved proposal will see a new annual season-ending World Cup of Tennis Finals that will crown the Davis Cup champions.
18 nations will feature and it will be played over one week in November.
Speaking after winning his US Open first round clash, Federer sent a warning to Pique about respecting the Davis Cup.
Federer told reporters: “For us tennis players it’s a bit strange to see a footballer come into our world. He should be careful.
"The Davis Cup should not become the Pique Cup.”
But Federer's issue with Pique could also be over the possibility of Davis Cup moving from November to September
Pique told France publication Le Figaro: "After talking with most of the players, most prefer the Davis Cup to take place in September.
"I want to set up a competition in accordance with what they want.
"All prefer September to November. The season is very long and they want the Davis Cup at that time.
"At Kosmos, we are working to find the best date for the Davis Cup in September."
If the Davis Cup is moved to September, it would be in direct competition with Federer's Laver Cup next year.

The Laver Cup, which sees Team Europe face Team World, is due to take place in Geneva, Switzerland in 2019, a few weeks after the US Open.
It is unlikely the top players will play both the Laver Cup and Davis Cup which could cause problems.
And Federer has confirmed talks will be held over the matter.
He said: "I'm in favor of innovation, and not everything is negative with the new Davis Cup.
"Now the ATP, the ITF and the organizers of the Laver Cup have to meet to discuss around a table."
