World number one Roger Federer made a surprise announcement overnight when he revealed that Australian Tony Roche will be his new coach on a part-time basis.
Roche, who coached Ivan Lendl and Pat Rafter to the world number one spot and several grand slam titles, will team up with the Swiss for around ten 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 2003.
