Boris Becker has insisted that Andy Murray has the quality to win over five Grand Slams before the end of his career.
The British number one recorded his maiden victory in one of the four major tournaments at the US Open earlier this month and Becker expects the 25-year-old to add to that triumph.
"Murray's always challenging," Becker said. "Three of the four Slams suit him, so I wouldn't be surprised if he wins two, three, four or five more."
Becker's comments echo those of Murray, who admitted on Monday that he has been spurred on by his success in New York.
