Andy Murray has not missed his chance to win a grand slam, and it is only a matter of time before he breaks his duck, says Boris Becker.

20196 - Andy Murray is too good not to win a slam - Becker

A six-time grand slam winner, Becker won his first major at the tender age of 17 at Wimbledon, but even at the age of 23, Becker insists Murray has time on his side.

"It's the million-dollar question," Becker told Sky Sports. "I don't know when but I think he will [win a major]. He's too good not to and he's getting close now and one of these days he'll do it."

Andre Agassi is one of only seven men to win all four major titles, and he lost his first three major finals before winning Wimbledon in 1992; Ivan Lendl won his first of eight majors at the 1984 French Open, but not before four failed attempts.

"You see the history of the game; Lendl, Agassi took a long time to win their first, so it is not unusual for a player to have a couple of tries," Becker said.
