Murray mania is already under way, as fans queued to get their chance to see the British number one play his first Wimbledon match this year.

Murray, 25, takes on former world number three Nikolay Davydenko on centre court as he begins his bid to become the first British man to win Wimbledon since Fred Perry in 1936.

The Scot will be hoping to prove the doubters wrong after putting in disappointing performances at the recent French Open and Queen's tournaments. But he has already secured the backing of six-time champion Roger Federer, who predicted he will reach the semi-finals for the fourth successive year.

And fans said they will be staunchly supporting him, regardless of doubts over his form.

Mark Martin was first in the queue for tickets, after arriving at SW19 from his home on the Isle of Lewis, Scotland, on Friday. The 46-year-old delivery driver said: "I think he'll definitely get through today. Murray's got a tough draw, no doubt about it, but all we can do is hope, can't we?"

Sisters Suzanne Pyefinch and Michele Jennings, from Great Yarmouth in Norfolk, arrived on Friday in the rain. They queued up today to make sure they could get tickets.

Mrs Pyefinch, 40, said: "I don't think today's going to be as big a problem as everyone makes out. It will be a good game."

Student Megan Evans, 27, queued up early with mother Jo, who travelled from Manchester to south-west London to get tickets.

"There's no certainties with him (Murray), but there are hopes, so that will do. This is how we support him," said Mrs Evans.

And she hit out at the anti-Murray lobby, adding: "If you support somebody else then support them but we don't slag them off so don't do it to him."
