Shanghai: Andy Murray can build on his breakthrough year by becoming the number one player in the world, top-ranked Swiss rival Roger Federer said on Sunday.
Federer said the Scot, who became Britain's first men's singles Grand Slam champion since the 1930s when he won the US Open last month, had bounced back strongly after losing the Wimbledon final.
"He's saying the right things. He has results that back up his chances to become world number one, maybe even at the end of the year, maybe at the beginning of the next year," said Federer. (Also read: Federer admits death threats distracted him)
