Here's a coaching idea that makes sense. But Federer with Rasheed?? Welcome to the latest ride on the coaching merry-go-round. Tony Roche looks set to become Lleyton Hewitt's new coach after being unexpectedly sacked by world number one Roger Federer. Roche, who also coached Pat Rafter for five years, had worked with Federer on a part-time basis from 2005 but is now expected to confirm his intentions to work with Hewitt as soon as his partnership with the Swiss is fully disintegrated. Federer meanwhile is rumoured to be setting up a partnership with either Darren Cahill or Roger Rasheed - both of whom have worked with Australian Hewitt. "If Tony Roche is available, we would be silly not to talk to him," Hewitt's manager David Drysdale said. "I'm not sure what Rochie's frame of mind is at the moment, but I'd like to talk to him, without a doubt. He's worked previously with Lleyton in Davis Cup with great success."
