Murray: I doubted I could win a grand slam until US Open

BRITAIN’S Andy Murray admits he doubted whether he would ever win a grand slam, before winning the US Open in September.

Murray’s bid to win the Barclays ATP World Tour Finals ended with defeat to Roger Federer in the final four on Sunday, but the Olympic men’s singles champion is convinced that his breakthrough year was worth the hard work.

“Sometimes when you lose a tough match or a big final, you spend the next few days thinking, ‘Is it worth it? Is all the training making a difference? Will I ever be good enough to win one of these big events?’,”said Murray, who lost four Grand Slam finals before his Flushing Meadows win.

“I’ve been through so many highs and lows already throughout my career, and to experience the sort of highs that I did in the summer made me realise it absolutely was worth it.”
