Selby, 23, won the last three frames to beat Shaun Murphy and become only the third qualifier to reach the best-of-35 final, starting at 1500 BST on Sunday.

He said: "I've got enough left in the tank. I am going to give my all."

Higgins, who came from 14-10 behind to beat Stephen Maguire 17-15, said: "It's going to be tough and nervy."

The 31-year-old will be seeking to avenge his shock 10-4 defeat by Selby in the first round in Sheffield last year.

He will go into the final with the advantage of having had longer to recover from his semi-final exploits.

His clash with his fellow Scot Maguire finished almost six hours before Selby's draining battle against Murphy reached its conclusion.

If I am going to be fazed it will happen in the first session Mark Selby

Selby says he will take inspiration from the fact that Murphy was also a qualifier when he won the world title in 2005.

"Players like Shaun helped me and he is a good friend," said the world pool champion.

"What he did was great and I'll use his experience to help me."

Selby, who beat another former champion Peter Ebdon in the second round, said he was confident of a good performance.

"If I am going to be fazed it will happen in the first session," said the Leicester player.

"The whole one table thing is a situation I've already been in."

Higgins said he was wary of the young talent coming through, but was confident that he still had the capabilities to match them.

"There are a lot of great, talented young players and they're getting stronger.

"I know time doesn't stand still, but I think I still have a lot to offer the game - a chance to win tournaments and play at a high standard."

He also believes the fact he has given up drinking has helped his career.

"When I had a drink in the past I didn't know when to stop - the British culture I guess," he said.

"There were times I'd go to watch Celtic then have a few drinks after football and go on to a club.

"Then I'd get a hangover and it took a couple of days to clear. Now that I've given up alcohol I'm feeling much better."
