Seven-time Wimbledon champion Roger Federer is here, everyone - and he's taken the picture to prove it.

He tweets:, external "2014 @Wimbledon is underway, #classic #exciting"

Federer, seeded fourth, faces Italy's Paolo Lorenzi tomorrow.

Curtains for Johanna Konta. The British number three was attempting to make up 49 ranking places on Shuai Peng. She made a decent fist of it, but came up short, losing 6-4 3-6 6-4.

Is that a red and black Belgian football scarf in the crowd down there? And why not - Goffin's most comfortable hold of the contest so far, Murray's tame backhand into the net sealing it to 15.

Shaquille O'Neal looks on on Centre Court, dreaming about pulling down the umpire's chair with a massive slam-dunking grab.

First little glimmer for Goffin - 30-30 on Murray's serve, second serve, no beef on it either - Goffin clouts to Murray's forehand side, but the Scot manages to readjust his feet and cream a forehand into the Belgian's backhand corner that he can only frame away.

"Andy is hitting the ball so cleanly. It is a delight to see - and to hear."

Alex Sim:, external Fantastic to see @andy_murray back on Wimbledon Centre Court as defending champion. Let the rollercoaster begin again.

Jamie:, external Murray looking so strong at the moment - bodes very well for the rest of the tournament.

Kimiko Date-Krumm is not letting Ekaterina Makarova, 14 years her younger, out of her sight just yet. The Japanese 43-year-old breaks back as Makarova serves for the match and we are back on serve at the business end of the decider.

Ernests Gulbis is still on course for a straight-sets win over Jurgen Zopp, but is making heavy weather of it at 7-6 (9-7) 7-5 5-5 up.

Britain's Dan Cox is 4-1 down in the opening set against Jeremy Chardy, while compatriot James Ward is down 6-2 2-1 against Mikhail Youzhny.

Goffin can't get his feet moving here - off-balance and out of synch for both a forehand and an over-balancing backhand that drifts well wide. Murray has two break points; Goffin wide again, this time off the forehand wing, and in the friends and family section Amelie Mauresmo allows herself the smallest of smiles.

38 minutes gone, and Goffin yet to wangle the thinnest foothold in Murray's serve. Murray wipes his face on a dark green towel proffered by a supplicant ball-boy, but he's barely had to break sweat so far - hold to love, on we go.

"Goffin twice had chances to move forward during one of the points in that opening game - and he didn't. He should be winning points like that. He's got to use his quickness to his advantage."

Johanna Konta is battling away gamely, but time is ticking away for the Briton against Shuai Peng.

Konta trails 4-2 in the final set, a single break down.

The umpire on Court 12 is adding a light touch to proceedings by pronouncing her opponent's name as "Pong". Is that really right?

Steve Guy:, external Murray could lose this match but Goffin cannot win this match.

Goonerama:, external Murray's sweatbands are completely redundant.

Goffin starting to relax a little, biffing a delightful backhand down the line to leave the champ swishing at warm air. Ace down the middle, and he's on the board early doors.

"Andy Murray hasn't put a foot wrong in this first set. Ideal day, ideal start to his defence."

Russell Fuller
BBC tennis correspondent on BBC Radio 5 live

"It looks as if there is little danger of Andy Murray following in the footsteps of Lleyton Hewitt, who lost to Ivo Karlovic in his opening match as defending champion in 2003."

Shaquille O'Neal, by the way, has size 23 feet. Murray rattles through his hold, the court sun-buttered, the crowd pinking in the afternoon warmth and entirely satisfied with the untroubled display they're watching.

Shuai Peng breaks the serve of Johanna Konta to take a 3-1 lead in the deciding set of their third-round match on Court 12. Can the Briton fight back?

Murray working Goffin over like a lean middleweight dismantling a naive sparring partner. Forehand after forehand forcing him wider and wider; the Belgian in to the net for a why-not joust, Murray flashing a topspin lob up and over his opponent's token reach. Lovely volley from Murray, moving through the repertoire and to within a hold of serve of the set.

Wince from Goffin as he slips on the lush grass and eats turf. Is that Shaquille O'Neal in the VIP slots? Pity the man sitting behind him. Straightforward hold for Murray, muted atmosphere.
