Chris Kermode has defended Roger Federer's decision to pull out of the open ATP Cup, insisting that the Swiss star is no bigger than the sport.
In January, an annual 24-country team competition starts over six days in Brisbane, Perth and Sydney.
There are $ 15 million prize money and a maximum of 750 singles and 250 doubles ATP Rankings available.
And the trip had managed to get the biggest names everyone committed to the event.
But late last month, Federer resigned from the Swiss team for "family reasons," and with Stan Wawrinka already out, the Swiss did not qualify for the event.
Ahead of the ATP final, Federer made his decision to pull out and said: "When we were to sign up for the ATP Cup it was shortly after Wimbledon, for me it was always a logical decision to play the first week.
“South America had the priority for me to be completely honest, but also the ATP Cup to play the first week.
"But when I realized that Stan was not going to play, the family would not travel to Sydney, honestly I said I would rather be home with the family and take it easy, train some more and prioritize the Australian Open and World Tour Finals.
“Something just had to give, and it was the ATP Cup. I would be very happy to play, but it wasn't that level of importance to me. Thats it. "Usually I don't make decisions like this, but I kind of got into the situation of having to make a decision after Wimbledon."
Creating the ATP Cup was one of Kermode's last moves before quitting as president and CEO after six years.
But speaking at a press conference, Eglishman said Federer had the right to make the best decision for himself.
"The events industry is kind of bigger than any player. You have to have that perception. You have to have that long-term perception," Kermode said.
"I talked to him a lot this week. Roger is 38. He's at the end of his career. I think what he's given the game has been quite astonishing, 100 titles.
"He's going to have to pick now that he's playing, how he's playing, and I think nobody expected him to play that long. And I think we have to respect that.
“Would it have been great if Roger played? Of course. But I think we have to respect that decision. He didn't take it lightly. "
