SIX-TIME Wimbledon women's singles champion Billie Jean King has tipped Scotland's Andy Murray to win the championship this year.

Speaking at the Edinburgh International Film Festival, where a documentary about her landmark 1973 match against Bobby Riggs – dubbed "The Battle of the Sexes" – had its premiere, King said Murray had everything it took to win.

"He's a great player, he should win Wimbledon, for sure," she said.

The tennis star, who has been seeded two at SW19, begins his fight for the men's singles title today with a match against Benjamin Becker of Germany.

King, the holder of a record 20 Wimbledon titles, first took note of Murray eight years ago.

"He's got every stroke. He's got great serves. He's got everything in the book," she added. "There's one shot I'd work on a little bit more, inside-out forehand, he tends to hook it a little bit, but you can always work on something."

King's match against Riggs in Houston, Texas, came about when the former male tennis champion said a woman player would never be as good as a man. King initially turned down the offer of a match, seeing nothing to be gained. But when Australian player Margaret Court took the bet and lost, King felt compelled to step in. Some 100 million viewers worldwide saw her beat Riggs in three straight sets.

Now 69, the player credited with ushering in equal pay for women in the major tennis tournaments has lost none of her fighting spirit. In Murray she sees someone with the instinct to be a champion.

"He did it at the Olympics, at the US Open. He's done it so he recognises it," she said. "If you've done something once you can do it again. That's what he should be telling himself, every single day; that I have won big matches, I have won big tournaments, I can do this."

The former world No 1 was legendary for her ability to play the big points. When Murray gets to those same critical moments he must keep pushing forward, she says. "He is good at being aggressive when he wants to be. Some players don't think they deserve to win. He deserves to win."
