Adrian Lewis is confident he can win his third PDC World Darts Championship title in a row despite a few troubles on the oche.
The 27-year-old is feeling good ahead of the North London extravaganza but admits his season hasn't gone entirely to plan.
Jackpot finished a disappointing sixth in the Premier League and failed to make a big impact at the recent Grand Slam of Darts and Players Championship Finals.
Now Lewis returns to the scene of his greatest triumphs and believes his top form will return for darts' number one tournament.
"I'm confident I can win it again," he told Sky Sports.
"I've had a patchy six months but my form will come good.
"I can't really put my finger on why (the form hasn't been there). Whether it's too much on the exhibition circuits or promotional stuff, I couldn't really tell you."
Lewis believes his previous triumphs at Alexandra Palace come down to "bottle" on the big stage and admits this is what all the hard work throughout the year is for.
"I think it's just about a bit of bottle," he replied when asked for the secret of his World Championship success.
"That's what it comes down to as it's the biggest tournament and everybody knows that.
"For some reason people don't perform as well as they should do but you've got to go up there and try and enjoy it.
"You put in the work all year just for that one tournament."
Phil Taylor has commented that Lewis is "under pressure" at Ally Pally and Jackpot is fully aware his former mentor is the main man for him to watch out for.
The 27-year-old also expects plenty of other top players to contend for the title but there is still belief that his ability will be enough to make it a hat-trick of titles.
"Phil Taylor is still the main man in my opinion," added Lewis.
"You've got Michael van Gerwen now who won the Grand Prix and lost in the final of the Grand Slam.
"Barney has just won (at the Grand Slam) so his confidence will be high.
"You've still got Gary Anderson, Simon Whitlock and James Wade, so it's a really tough field.
"But at the end of the day if you don't believe in your own ability it isn't worth you being there."
