Johannesburg [South Africa], Nov. 9 : Former world number one Stefan Edberg believes Roger Federer, who has fallen outside the world's top 10 for the first time since 2002, is still capable of beating the best and winning another grand slam title.
The Swiss ended his season in July in a bid to recover fully from knee surgery, although he is aiming to be fit for the Australian Open in January.
Ever since then, there have been significant changes at the top of the ATP Rankings, with Andy Murray rising to World No.1 replacing Serbia's Novak Djokovic.
Meanwhile, the 17-time grand slam champion has slid to 16th spot in the men's rankings. But, Federer's former coach believes that the Swiss legend can win at least one more grand slam. "I thought in the past years he would have won one, he was so close," Edberg was quoted as saying by Sport24.
"It becomes even tougher, he is not young anymore but there is still hope. If there's one who can do it, it's Roger, but it will be an emotional challenge for him to come back next year," he added.
