On Luis Suarez: "In baseball we have three strikes you're out. This guy has done this three times, he can't help himself. He's a great football player there is no doubt about that."

Next big American player? "I always thought John Isner would do well at Wimbledon, anyone who served that big should be able to do something. I have a good kid Noah Rubin playing at my junior academy. Tony Mo's son, Michael Moe, keep an eye on him."

Tim Stubbs:, external My upset is far more recent young Andrey Kuznetsov beating no.7 ranked Ferrer. A wonderful five setter, a great result for the world no.118.

John McEnroe now reveals that he and Boris Becker have a dinner riding on the result of today's World Cup clash between USA and Germany.

Hate to say it John, but I think that Boris might be searching around for the priciest fillet and Chateauneuf du Pape in London town.

Here are some of the John McEnroe's early answers to listeners' questions. It is worth tuning in though just to hear him wrestle with the pronunciation of callers' home towns.

Grunting by tennis players? "It's necessary when you're over 50 but I don't get it here. Some might think it's cool because you feel they are into it but often it's way too much."

Coaching role?: "I would consider it, not a full time job 30 or 40 weeks a year but part time.

"Another of my six children is about to go to college so that leaves only one now, so in a couple of years time my wife is going to be begging me to take a coach's job."

He is currently laying into a caller, questioning their analysis of tonight's United Stats v Germany World Cup action.

John McEnroe and Tim Henman are on the roof of the Broadcast Centre at Wimbledon answering your questions on 6love6 on BBC Radio 5 live.

He is still the coolest dude in SW19 isn't he? Admittedly perhaps not the most competitive postcode.

Raonic 5-2 Sock: Milos Raonic, the eighth seeded Canadian, is a break up on American Jack Sock.

Gasquet 6-3 0-1 Kyrgios: Richard Gasquet takes the first set against Australian wildcard Nick Krygios.

Siljestrom/ Zelenay 4-6 Marray / Smith: Britain's 2012 doubles champion Jonathan Marray and his Australian partner John-Patrick Smith have lost the first set of their first round tie.

D Kudla 3-5 K Nishikori: Tenth seed Kei Nishikori noses ahead on court 18

"Andy Murray, have you ever been to Wigan?"

Never afraid of asking the questions that the others have never even thought of, Hacker T Dog has got his claws into the Wimbledon defending champion.

You can see the resulting carnage on BBC iPlayer - 16 and a bit minutes in.

By the way, Andy hasn't been to Wigan, but would love to go.

"Anyone for head tennis? This family from Bristol caught the eye with their Wimbledon themed headgear."

BBC Weather's Carol Kirkwood: "It's high cloud and it will break and there will be some sunny intervals, with temperatures around 19 or 20. Even into the evening it should stay dry, the light may deteriorate and then after dark there will be some rain around but that won't affect us here of course. Pollen levels will be going down over the next couple of days."

Laura Robson
Injured British number two on BBC TV

(On facing Heather Watson's opponent today Angelique Kerber) "When I played her (in 2011) I hadn't won a match at Wimbledon so I was super nervous and we were on an outside court. Angie has won a couple of titles since then and has kept that form. She moves extremely well and can keep the rally going. Heather has to be really aggressive, like she was in the first round, and not get caught up in the situation."

Lawrence Barretto
BBC Sport at Wimbledon

"Britain's Heather Watson, who meets 2012 semi-finalist and ninth seed Angelique Kerber in the second match on Centre Court, is down at the practice courts for a morning hit.

"She kicks off with 15 minutes of stretching and resistance work which involves using a small medicine ball, a resistance band and a foam roller - but not all at the same time."

Andy Murray is currently down on the Wimbledon practice courts to do some homework ahead of tomorrow's third-round meeting with Roberto Bautista Agut.

What does he get up to post playing though? Well, his Wimbledon dinners are on a three-day cycle, he takes his bananas mashed and between bagel halves and just occasionally he catches some tennis.

Former British number one on BBC TV

"It's the toughest thing in our sport - men's or women's - to come back from winning the French to winning Wimbledon. Next year there will be a three-week gap but it's still unbelievably tough. I think Rafa will be okay today but it's a dangerous match for him.

"Roger Federer you can't write off, but Gilles Muller is also dangerous opponent for him. The talk is all Djokovic and Murray but Feds has got Edberg in his corner and he is looking good."

Stephanie Siu:, external Despite not being Rafa's number 1 fan, I LOVE Uncle Toni.

Matt Bone:, external Wonder if I'll get told off again this afternoon for trying to get a "Go Genie Go" chant going in the office?

Uncle Toni might sound like the face of a pizza restaurant, but Rafael Nadal's coach was handing out cups of Wimbledon's official coffee earlier this week.

While he was doing so, my colleague Lawrence Barretto grabbed a few words with him on today's match.

"That defeat cannot affect the match," said Toni. "I think Rafa is better now than he was in 2012."

Nicola Jade:, external Didn't realise the Tsonga/Querry match had gone to 5sets! Similarities to Isner/Mahut...Definitely worth a watch then!

Daniel W:, external Finally get to see Federer at Wimbledon today after missing out on tickets for 10 years!

Charlie Clinton:, external Does anyone think Lukas Rosol can do it again? Up first on centre vs Nadal!

(Re Rosol's win over Nadal two years ago) "It was one of those stunning matches. Rosol was seeing it like a football and you were thinking 'it can't go on' but it did. Rosol didn't care who he was playing that day and he was in the zone from beginning to end."

With the players knocking up around the grounds ahead of the start of the day's play, BBC Two have fired up the transmitter and are broadcasting live from the All England.

First on the agenda is Rafael Nadal's rematch with 2012 conqueror Lukas Rosol.

BBC Sport's James Burridge on Twitter:, external "Eugenie Bouchard has the attitude to go all the way at Wimbledon. Today plays WC Soler-Espinosa. Possible clash with Serena in R4.

I'll get the ball rolling. 2001. A 19-year-old Roger Federer, who had lost in first round of his last two trips to Wimbledon, downed defending champion Pete Sampras, who had not lost at Wimbledon since 1996.
