Impressive Murray marches on
By Andy Murray
World number four and British number one
It's definitely exciting to be in the quarter-finals of Wimbledon but it's easier to handle the situation now as I've been through it a couple of times before.
This will be my sixth Grand Slam quarter-final and the more you play, the easier it becomes to deal with.
After you win a match you're obviously excited but the adrenaline goes and there's a bit of calm for a day and a half, and then before I play Jo-Wilfried Tsonga the excitement will rise and the adrenaline will return on the morning of the match.
In the first three rounds I served really, really well but on Monday it wasn't so good, so I was just glad that the rest of my game was solid because, if not, it could have been a different story as Sam's been playing really well.

I was happy I only lost my serve once, although because I was up 40-15 and serving for the set it was a bit disappointing.
It's definitely easier than it used to be for me to get over moments like that quickly but you can certainly lose your way sometimes when you play a bad game.
You're not going to serve well every day, on others you won't return as well, and the more matches you play at this level the more you understand that, if you lose focus a little bit, there's a good chance you're going to lose games or get broken. It's not something I'll dwell on though.
After a match I'll usually have a brief five or 10-minute chat with my coach Miles when I'm warming down on the bike about what went well, things that could have been a little bit better, but when you're in the middle of the tournament it's important to try and stay as positive as possible.
You're not going to improve your game when you're in the middle of a Grand Slam; all the work should be done before you get there. At the end of the tournament we'll sit down and view the tournament as a whole - what went well, what needs to get better.
For now we concentrate on the next challenge, and Miles went to watch a bit of Tsonga and Benneteau's match on Monday to see how they were playing.
Murray's Magic Monday Moments
On Tuesday, I'll try and sleep in as much as possible, until 10.30am or 11.00am, before heading in to practise at 1pm and see the physio.
I always sleep well - I've never had a problem not sleeping through nerves - but when you get up on the morning of a match there's a different feeling. The butterflies are going and you don't feel as hungry as you do when you wake up most mornings.
I'll chat with Miles for 10 minutes on Wednesday about Tsonga and how he plays, what things have worked well when I've played him before.
Miles keeps a book with notes on all the players I've played against so I've got a pretty good idea when I go on the court of what I need to do.
In terms of the timing of my matches, as long as its not too early I don't mind.
The perfect time to play on Centre Court is usually between 2.30pm and 5pm because, as the sun comes down, it can be difficult to see when the ball's coming in and out of the shadows.
But thankfully at Wimbledon there's no chance of me having to play at 11am, because I'm normally sleeping, and from 1pm onwards it's not a problem.
