This French Sports news website is confirming (up to now) rumors on Roger-Cahill teaming up. It's in French though: http://www.7sur7.be/7s7/fr/1513/ten...ederer-sous-les-ordres-de-Darren-Cahill.dhtml Here is how google translated it: Under the leadership of Jose Higueras in April 2008, Roger Federer has decided to end its collaboration with the former glory of the Spanish tennis. Australian Darren Cahill will take under his wing prodgieux the Swiss player, recent winner of the U.S. Open. Federer and Higueras split because the Spaniard has the opportunity to work with the American Federation, which would have made a tempting offer. Cahill, former coach of Lleyton Hewitt and Andre Agassi, has so far been based commentator with the Australian television channel ESPN. . In 2003, Federer had appealed to Cahill for the first time, but Australia had refused his proposal. The Swiss is now finalizing a contract. Maybe they have some inside info, maybe they don't. As far as I am concerned it remain as speculation until Federer, Cahill or a credible source confrims this.
