Exciting news! Besides being a father again in 2014, Federer has also said that he will use his childhood idol Stefan Edberg as a coach for at least ten weeks starting from Australian Open. And he will be using the larger head size racquet he was tinkering with in 2013 permanently!
Two quotes from the maestro himself (source tennis.com):
“I am happy to announce that beginning in Melbourne, Stefan Edberg will join Severin Lüthi on my coaching team,” Federer said on Facebook. “Severin, who has been part of my team for the last 7 years, will do most of the weeks and Stefan has agreed to work with us. Stefan was my childhood hero, and I am really looking forward to spending time and learning from him.”
“The racket is extremely important,” said Federer, who experimented with a new frame last summer before going back to his smaller frame at the U.S. Open, and for the rest of the 2013 season. “But now I have the feeling that this is the right time for a change. I’ve played through two and a half weeks with the new model and am confident. The racket suits me very well.”
