Federer to face Nadal in semis

Callum Allison:, external Despite wanting Andy to win, it is brilliant watching Federer playing like this again.
Joseph Burns:, external If top players like Murray and Tsonga struggle against Federer's serve & volley tennis then perhaps Henman should make a comeback.
Jack:, external Federer in full flow is still the classiest player to watch.
Image source, APMurray is really struggling to hold on to Federer here. The Scot removes his cap and wipes his brow as he finds himself break point down for the second time in the match. It's a decent serve, but Murray then sends a backhand ailing long to gift Federer the break. Oh dear.

Dave Oswald: After his surgery and lack of match fitness I would be very surprised if Big Andy won this one. But come on Andy anyway.

"Andy is getting there, he's getting closer and moving Roger around."
Murray carves out his first real opening of the match with 15-30, but Federer takes Murray's return so early, the Scot has no chances of scrambling across the court to retrieve it. A tasty serve, which hits the right corner, brings up game point before a simple forehand closes it out. Murray places his racquet up to his mouth and grimaces.
Image source, APIt's a great approach from Murray, who is trying to be more aggressive in the second set, but he's left deflated as Federer rustles up a forehand passing shot, of the highest quality, down the line and on the stretch. Still, Murray is ultimately rewarded with the game as Federer dumps a forehand into the net.
Irshad Bhat:, external Can't believe people are writing Federer off. When Roger is at his best Murray is no match to the skill and art of Federer.
Laura Lambert:, external Trust Murray to come back, he won't roll over to Fed. Terrifyingly different level to his previous four rounds though. Five-set thriller.
Andy Roberts:, external Ronnie O'Sullivan was compared to an artist this week, Roger is the best player ever to have played - more Godlike!
Federer is taking a whopping 89% of points on his first serve at the moment, in comparison to 69% for Murray, and that formidable form continues in his first service game of the second set as he comfortably holds.
Murray exhales a deep breath and raises his shoulders slightly, as if to say he doesn't quite know what to do. Another mishit backhand is eaten up by Federer to bring up 30-30.
But then comes the best and longest rally of the match - at 23 shots - which sees both players scrambling and battling to wrestle control of the point.
Murray reaches for a backhand volley, and makes it, before heaping the pressure back on Federer. Eventually, it's the Swiss who breaks down, and Murray takes the next to seal the game. Big point. Big hold.
Piers Newbery

"Another wonderful set of tennis from Federer, who missed two first serves in his opening four service games, which didn't leave much for Murray to go at. Half an hour gone and Rod Laver Arena is still filling up with latecomers, who were taking a bit of a risk. Federer isn't hanging about."
Chris Harmer:, external Roger Federer looks like he's rewound about eight years.
Azhar:, external It's a joy to watch Federer coming to the net more than he used to.

"It's a tactically perfect set from Roger, he could not play better. Every aspect of the game he played perfect, he didn't give any rhythm to Andy, he served well, volleyed well. It's beautiful to watch."
This is a new Roger Federer which we're witnessing right here. The Swiss is doing all the hitting and utterly dominating the points. That's encapsulated in the third point when he follows up a couple of heavy groundstrokes with a blistering forehand crosscourt winner.
His forehand, which is working an absolute treat, helps him seal the game - and the set - to love. Marvellous tennis from the 17-time Grand Slam champion.
A few errors are starting to creep into Federer's game which allows Murray to hold serve and force the sixth seed to serve for the set.
Gregg:, external Murray is the younger man, needs to hang on while Fed throws everything at him. Long way to go.
Luke Waterhouse:, external Mighty Fed to wrap this up in 3.
Michael Lee:, external My money is on Murray for this one. Think he will have too much power for the over the hill Federer today.

"From the first moment Roger has stepped up to the net. He doesn't allow Andy to get into a rhythm and Andy doesn't like that."
Federer has been to the net 12 times already and the match is a little over 20 minutes old. But it's working. Murray gives himself a chance with a stretching crosscourt backhand winner, which Federer can only watch sail by, but Federer hits straight back with a stunning drop volley. And it's that booming forehand of Federer's that helps him kill off the game.
Image source, APFederer keeps on rushing to the net, but at last, Murray seems to have got his trademark passing shot working. The Scot whips a beauty down the line to bring up game point and closes it out courtesy of a Federer error.
Federer is well on top at the moment, the Swiss rushing to the net at every opportunity. Murray isn't coping so well with the Swiss' attacking gameplan and Federer consolidates the break with a tidy hold.
Goran Ivanisevic
Former Wimbledon champion on BBC Radio 5 live sports extra
"Very smart play by Roger, taking advantage of every short ball that Murray gives him, stepping in and coming to the net."
