is all set to go in search of another title and the huge amount of prize money that will come with it. The Nuke is the defending champion and has the chance to become the third player in history to win back-to-back titles. At the moment, and are the only members of that exclusive club.

The teenager superstar has emerged as the face of the sport following his incredible breakthrough at Alexandra Palace last year. Over the last 18 months, he has won a number of tournaments and raked in plenty of prize money. If he claims a second Premier League title on finals night at the O2 Arena, he will add another £275,000 to his growing bank balance.

Express Sport takes a look at Littler's career earnings to date and how much he is estimated to be worth...

Littler is already up there with the highest-paid players on the planet, having won £500,000 for being crowned world champion. In total, he has pocketed just under £1.5million since bursting onto the professional scene.

Around £1.1m of his winnings have come from ranking events, including the UK Open, Belgian Open and World Darts Championship. Results on the European Tour, Players Championship, World Matchplay and World Grand Prix are also included.

Littler also won the Premier League and the World Series of Darts last year, claiming another £395,000 in prize money. Those events are invitational, though, meaning they do not count towards his ranking on the PDC Order of Merit.

However, by adding the £1.1m from ranked and the £395,000 from non-ranking events, it puts Littler's grand total at £1.49m.

It is unclear how much Littler is worth overall, but it is safe to say the 18-year-old is comfortably a millionaire. A decent chunk of his money is coming from lucrative sponsorship deals with the likes of Target Darts, Xbox and BoohooMAN.

It seems likely that further commercial agreements will be on the horizon, given Littler's status as the biggest name in darts. He has almost single-handedly given the sport an entirely new profile and looks set to lead the way for years to come.

Littler has used some of his newly-found wealth to move his family into a luxury house in Warrington, which comes with its very own swimming pool. He is believed to be forking out around £6,000 per month in rent.
