Federer is a strong favourite to win Wimbledon in 2009 after he equalled Pete Sampras' overall record of 14 grand slam titles by winning French Open. Federer knows that reclaiming his crown will not be easy, especially with Murray improving fast.
"Andy Murray's best surface might be grass - I think he's playing excellent," The Guardian quoted him, as saying.
Murray begins his preparations on Wednesday, Jun 10 when he plays the Italian world No.48, Andreas Seppi, in the second round of the Aegon Championship at Queen's Club in London.
In the absence of Nadal, the Scot is the No.1 seed here and is in good heart after his run to the quarterfinals at the French Open. He would do well not to take Seppi lightly, though.
"I actually lost to him the only time we played on grass in Nottingham a few years ago," Murray said.
"He is an experienced player but I've played well on grass the last few years so if I can start well I've got a good chance. I haven't had that much preparation, so I need to be realistic about my chances and just try and focus from the first match.The grass takes a few days to get used to, but I've felt good practising on it so far," he added
