Federer fires ominous Djokovic warning to rivals
Roger Federer has fired an ominous warning that US Open champion Novak Djokovic is still short of his very top form.
Former world number one Djokovic ended a two-year wait for grand slam glory by winning Wimbledon in July and added a 14th major title at Flushing Meadows this month.
That latter triumph saw him move level with Pete Sampras on the all-time list of male grand slam triumphs, the pair ranked third behind Federer (20) and Rafael Nadal (17).
But Federer believes that Djokovic still has more gears to reach having recovered from the injury and form woes that saw him lose his grip atop the rankings.
“I think that there’s more to come from Novak,” he said at an event held by the Andy Roddick Foundation in Austin.
“I don’t even think he’s playing his absolute best since his injury. He’s playing very, very well.
“In his best years, a few years ago, when he was almost, virtually, unbeatable I still think he has a little bit extra to go, so I think it’s very encouraging for him.”
