DOHA, Qatar -- Roger Federer made a surprise announcement on Tuesday when he revealed that Australian Tony Roche will be his new coach on a part-time basis.
Roche, who coached both Ivan Lendl and Pat Rafter to the world No. 1 spot and several Grand Slam titles, will team up with Federer for around 10 weeks in 2005.
Federer, who won three of the four Grand Slam events last year, has been without a coach since parting with Swede Peter Lundgren in December 2002.
The arrangement with Roche is initially for one year, and Federer -- who began 2005 with a 6-1, 6-1 win over David Ferrer in the Qatar Open on Monday -- said the decision was a relief.
"It's good to know that there will be help there because I need someone to analyze and help improve my game," he said.
Roche had previously turned down the chance to coach Federer when the Swiss player asked him in February 2004 because he did not want to travel too much.
