Former British number one on BBC Radio 5 Live
If you look at their Grand Slam tally they have won 53 between them - that's 13 years' worth and emphasises how dominant they've been. For Stan Wawrinka and Andy Murray to win three slams in this generation is a great achievement.

Djokovic v Goffin
Marion Bartoli
Former Wimbledon champion on BBC TV
Biggest banana skin of the men’s quarter-finals? That is a tough question – I would go with Novak Djokovic against David Goffin. First of all Goffin is really playing some great tennis, plus Novak keeps on sending really nice messages about him, saying he is one of the best movers on the tour. And I think that when you have someone who keeps on winning so many matches and moves so well on grass, he is always very dangerous.
Now is Novak going to lose? I don’t think so, but that could still be a very tough one.

Former Wimbledon champion on BBC TV
Getting to the quarter-finals means you're in the big league - for a couple of guys and girls it's the first time they've been here. You usually see the legends, the champions, but also a few people coming through. Guido Pella is a lefty, crafty with his shots. The threats are there, because there are good players playing the top guys.

Image source, Getty ImagesOne of the highlights of this year's Wimbledon has been the mixed doubles pairing of Britain's three-time Grand Slam singles champion Sir Andy Murray and 23-time major winner Serena Williams.
They're in action once again today, as they take on top seeds Bruno Soares - the former men's partner of Jamie Murray - and Nicole Melichar.
But, in the meantime, we want to know: what would your dream tennis doubles line-up look like?
If you're stuck for ideas, in the past a legendary all-British pairing of Jo Durie and Jeremy Bates claimed victory at Wimbledon - though we're not necessarily restricting you to tennis players alone...

Meanwhile, former number one seventh seed Simona Halep is through to the semi-finals at Wimbledon for the first time since 2014 after a 7-6 (7-4) 6-1 victory over China's Zhang Shuai.
The 27-year-old 2018 French Open champion fought back from 4-1 down to take the opening set before cruising the next.
She will play eighth-seeded Ukrainian Elina Svitolina, a 7-5 6-4 winner over Karolina Muchova, in the last four.
Konta reacts to a journalist's 'patronising' question after her defeat to Strycova
So one of the talking points from Tuesday was the reaction of British number one Jo Konta to the questions asked by a journalist who was challenging her big-point mentality.
Konta lost 7-6 (7-5) 6-1 to unseeded Barbora Strycova in the Wimbledon quarter-finals.
She hit 33 unforced errors in a match in which she was the overwhelming favourite, mirroring a similar showing in the French Open semis.
"I don't think you need to pick on me in a harsh way," she told one reporter.
