Andy Murray is now a legitimate contender to win this tournament.

John McEnroe:

Andy Murray is now a legitimate contender to win this tournament.

Once he got through his early nerves against Juan Carlos Ferrero, he just slipped into top gear.

As soon as Murray got into the match it was like someone put a pin in the Spaniard's balloon.

The way Andy played the last 40 minutes and returned serve was pretty frightening.

Tim Henman:

It was such a complete performance from Andy.

It's going to be very difficult for anyone to beat him, and I fancy his chances going forward.

His serving was back on song and he won 88% of his first serves. And when he returns like he did against Ferrero, he is so hard to play against.

After his long five-set match against Wawrinka, he's done well to come back so emphatically and play the way he did.

Michael Stich:

This was a very convincing display from Andy.

Only at one point, at the beginning of the second set when he had a lapse, did it look in any doubt.

When Andy steps it up and plays at his top level, there are very few players who can really compete with him.
