Federer, owner of a record 17 Grand Slam titles, says Friday on Facebook that six-time major champion Edberg "agreed to work with us for at least 10 weeks starting at the Australian Open."
“I don't see him as much as a coach, I see him more as an inspiration, a legend joining my team," Federer said. "We both don't know what it’s going be like. No big expectations, but we are going to have a good time together.”
Federer refers to Edberg as his "childhood hero." Severin Luthi will continue to work with Federer, too.
In October, Federer split with coach Paul Annacone after 3½ seasons together.
Federer finished 2013 ranked No. 6. It's the first season since 2002 he didn't reach a major final.
The Federer-Edberg announcement comes a little more than a week after Novak Djokovic hired Boris Becker as a coach. Andy Murray already had been working with Ivan Lendl.
