Roger Federer called for a merger between the two governing bodies on Wednesday on social media with the men's ATP Tour chairman Andrea Gaudenzi and his women's WTA Tour counterpart Steve Simon both welcoming the suggestion.

"At the moment, as a fan of tennis, if you want to try to follow tennis, whether it's Davis Cup, Fed Cup, the WTA, the ATP, smaller events, there are so many different platforms a fan has to subscribe to and it's confusing," Cahill said.
