Selby pointed at smiling wife Vikki in the crowd as he crossed the winning line, joy and satisfaction detailed across his face. She and daughter Sofia joined him amid ticker-tape trophy celebrations.

"It's fantastic. I'm just really happy to win," Selby said. "I saved my best performance for the final."

The 6-0 lead that Selby established on Sunday was whittled down by determined Ding, who was determined not to squander his big chance, but ultimately he could not overhaul the world number one.

China's first finalist in snooker's premier tournament clawed his way back to 10-9 and 11-10 during Monday afternoon, but going level proved beyond him each time.

Selby led from start to finish and was a worthy champion, collecting snooker's biggest ever prize cheque of £330,000 to go with the silverware.

It was Ronnie O'Sullivan that Selby saw off in 2014, when he staged a terrific second-day fightback to scoop the title. This time Selby was in charge and had to deal with that very different pressure, beginning the day 10-7 in front of a player whose dip in form over the past year meant he had to negotiate the qualifying rounds.

Ding had tens of millions watching him on television in Asia, where he is just as revered as O'Sullivan.

And at times during the contest he rolled back time to when he was the world's number one player, making three century breaks - strangely 103 each time.

Selby took a month off the tour for personal reasons before heading to Sheffield, and at times that absence showed in his game, but come the final he had brushed off the rust.

After Ding's early nibble at his lead on Monday, Selby began to fire. He had breaks of 126, 52, 68 and 55 in pulling 14-11 clear heading into the evening.

It was cleared how much it mattered to him too. He swished his cue in anger at one point after missing a testing pink.

And the contest looked to be in its final throes once Selby took the opening two frames on the resumption.

Not so. Runs of 73, 70 and the third 103 of the match revived Ding's prospects.

Early risers for breakfast in China, joining those pulling small-box snooker all-nighters, would have been willing the momentum to drive Ding ever closer.

This great tournament has never had an Asian champion, with Ireland's Ken Doherty, Australia's Neil Robertson and Canadian Cliff Thorburn the only overseas title winners of the 1977-onward Crucible era.

Despite living in the Steel City for the last 10 years, the Crucible is a venue for which Ding has shown little love in the past.

He was longing to have his name engraved on the trophy this time though, but Selby was not going to yield.

He battled through one scrappy frame with an iron will and then clinched victory rather more stylishly with a 74 break.

Selby expressed surprise at joining the illustrious club of two-time winners, admitting he had seldom managed to hit top form throughout the two-week tournament.

He said: "Apart from the last session of my semi-final against Marco (Fu) it's been average or lower than average.

"I think it's just grit and determination. I never seem to give in no matter how badly I'm playing. Until the final ball's potted I still keep believing inside that I can win.

"Some players let their heads go and get a little bit downbeat, but if anything it inspires me a little bit more."

Selby, who endured a less than ideal build-up to the tournament having taken time off the tour to resolve personal issues, said winning his second title was particularly special.

He added: "I never dreamed of winning it twice - the first time is always special, especially the World Championships, and it will always have a special place in your heart.

"But when you look at the people who have won it twice, not many players get to join that elite group so it is something very special.

"I definitely didn't feel match-sharp coming into the tournament. I practised back home but I was sort of coming in blind so I didn't know how I was going to play.

"I knew I had to capitalise early doors and I seemed to do that. Ding showed what a great player he was to come back into it and get back within one frame at times, and I managed to dig deep and get myself out of the hole."

Ding vowed to learn from the experience after eclipsing his previous best performance of reaching the semi-final in 2011.

The 29-year-old, who had to fight his way through three qualifying rounds to reach the Crucible, has done enough to book his place back in the world's top 16 next season.

Ding said: "Five years ago I was in the semi-final and this year was one step up, so maybe next year I'm going to win it.

"This season I've been working with Terry (Griffiths) and I think I've improved my game a lot. If I keep playing like that I will win more tournaments."

Ding admitted his chances of reaching the final were hit by his nightmare start which saw him lose the first six frames before clawing back into the match.

He added: "I played well in the last session and I played like I was enjoying it more.

"My start was very bad - 6-0 down was too far away for me, in the final especially. I had good chances to come back but he went on to win every big frame."
