Ahead of the start of the ATP World Tour Finals this weekend, Andy Murray has spoken of his determination to show his top form from the very start of the tournament.

The British No.1 is hoping to finish 2011 on a high with victory at the O2 arena, something many placing free bets online believe he can do. It will not be easy though, all of the world’s top players are in action, and Murray knows he needs to be on top of his game.

Speaking ahead of the tournament, he said: “You have to be right on your game from the first match. Sometimes you work your way into an event. Here you have to play your best, simple as that.”

Murray – who faces David Ferrer on Monday – then spoke of the high calibre of which he holds the ATP World Tour finals, describing winning it as ‘one of the biggest’ achievements in tennis.

The Scotsman continued: “It's one of the biggest tournaments on the tour - you're competing against the top guys.”

“If you can win, it's a big achievement, one of the biggest. So there's a real incentive.”

“This is different from other tournaments because you have to play well - very good tennis - from the first match if you're to have a chance of going through.”

Murray clearly enjoys playing at the O2 too, having won 27 of his 29 matches at this venue.

“I am most comfortable playing indoors because that is what I grew up playing on. Last year I lost in the semis but played a great match against Rafa.”

“In some ways maybe losing that match gave me the drive to work harder and make sure things improved.”

"As long as I finish the year playing good tennis, that makes a difference going into the off-season.”

“None of the matches are easy and there's no group you're going to get that's going to be much better than the other one.”

“I've played well against Ferrer on hard courts in the past but he's made the final before [in 2007] and he has won tournaments on indoor hard courts.”

"Berdych played very, very well in Paris and obviously Novak, even though he's had some injury problems the last few weeks, has had an incredible year. It's going to be a tough draw, with long points and long matches.”

It should be extremely entertaining too. It is always faced paced tennis at this event, with the players interacting with the crowd and revelling in the excellent atmosphere.

Before Murray faces Ferrer on Monday, the tournament gets underway with Roger Federer playing Jo-Wilfried Tsonga and Rafael Nadal up against Mardy Fish on Sunday afternoon.
