Eugenie Bouchard, speaking to BBC Sport following her 7-6 7-5 win over Alize Cornet: "I am really excited and proud of the way I performed. It wasn't easy, Alize is a great player and got so many balls back so I had to work really hard.

"I am very exited about reaching the quarter-finals but I need to stay focussed and not get distracted. This is what I have worked so hard for but I cannot get carried away and distracted."

"Eugenie Bouchard just had too much power Alize Cornet, who was excellent in beating Serena Williams. She played a great match and she must really fancy her chances now for the tournament."

British number two Laura Robson, currently out of action with a wrist injury, answered you questions on the BBC Tennis Twitter account earlier today. These are the final bits and piece of what she had to say for herself.

David Ferguson: Laura, GB tennis is lucky to have both you and Heather Watson. Are you two friends, rivals, or a bit of both?

Laura Robson: Friends! We're happy when the other does well but when we play each other we're rivals. I've played lots of doubles with her

Brandon Wheeler: When do you think you'll be back playing competitively?

Laura Robson: Hopefully at the end of the year, but I don't want to put a date on it just yet.

Sabine Lisicki tells BBC TV how she is looking forward to her fourth-round clash with Yaroslava Shvedova:

"I have had a great few matches so far, she is playing well on grass and has a big serve, but I'm looking forward to it. The fans here are amazing, the energy out there is fantastic and I am having so much fun here."

Cornet's game has unravelled in the last few minutes and she now finds herself 0-30 down. She rescues the next with a deft touch on a drop shot but soon finds herself match point down as a forehand slice goes wide.

And it's all over when Cornet sprays a backhand long to gift Bouchard the break and then match. Bouchard clenches both her fists and fires a smile up to her box.

"You just get the feeling Lisicki would want all WTA tour events would be on this surface, it suits her game and she moves so well on it.

"The draw looks pretty wide open for her, Simona Halep is the highest ranked opponent left in her half, but Maria Sharapova is playing with so much confidence and really looks fresh to me."

Sabine Lisicki: "She hit amazing winners before the rain, after I think we both were hitting them, but maybe I managed a few more! The crowd here give you such amazing energy, it is a joy to play here and it makes me feel at home."

Sabine Lisicki has been smiling for most of the match, but the German 19th seed breaks out the full Cheshire as she wraps up her fourth-round spot with a solid service game.

Bouchard opens with a sensational drop shot from just inside the baseline which Cornet can do nothing about. There's nothing to choose between the duo in the next three points before Bouchard whips up a bit of magic to get break point.

Cornet saves it with a huge forehand, clenching her fist and shooting a glare to her box, but back comes Bouchard with another break point. And this time, she gets it as Cornet fires wide. We're back on serve.

"Rain? What rain? Bright sunshine now at SW19, so warm I may consider shedding a layer. In these parts, sun means that fruity alcoholic beverage (you know the one) but, at £7.80 a glass, some favour the DIY option. I've just spotted on chap pouring lemonade into the aforementioned beverage contained in an old water bottle. A man after my own heart."

John Isner has already played four tie-breaks in just two and a bit matches at Wimbledon this year.

The American looks like he is heading to another shoot-out against Feliciano Lopez over on court three.

Cornet will have to serve for the set as Bouchard holds to 30. Andy Murray is due on court after this match. I suspect he won't be in action until gone 16:00 BST if this goes to a decider.

Smiling assassin Sabine Lisicki has chiselled a break from Ana Ivanovic over on Court One.

Last year's runner-up has made the last eight or better in all her last four visits to the All England.

Cornet going to the Bouchard backhand and it pays dividends as she recovers to 30-30. The Canadian then lets the game slip with two forehand errors and will now serve to stay in the set.

Over on Court Two, 2011 champion Petra Kvitova has opened up her match against China Shuai Peng.

The Czech sixth seed is a good pick to "go deep" over the next week. She will play Barbora Zahlavova Strycova if she wins today before a potential semi-final clash with Agnieszka Radwanska.

World number 16 Caroline Wozniacki, who was beaten 6-2 7-5, external by Barbora Zahlavova Strycova, on Twitter: It wasn't to be this time. Thanks for all the support this week, it's been amazing!

Big hold from Bouchard who sends a forehand fizzing down the line to win the game to 30.

Cornet is oozing confidence after that break, rattling through her service game to love. Bouchard looks up to the sky in search of answers.
