Littler’s run to the Ally Pally final banked him an eye-watering £200,000 in prize money. Subsequent victories at the Bahrain Darts Masters and the Belgian Darts Open, as well as several other impressive tournament performances, have boosted his total career earnings even further.

Just a matter of weeks after achieving darts stardom at the world championship, Littler signed a multi-million-pound deal with clothing retailer boohooMAN. Manchester City star Jack Grealish and former England man Dele Alli are among the company’s other collaborators.

And now, Littler is pursuing a new side hustle by selling match-worn shirts to his millions of followers. According to The Sun, replica jerseys start at £89.99.

But for those with the means to splash out, framed shirts are up to £239.99 and match-worn options are also available. At only 17 years old, Littler was effectively unknown before bursting onto the scene at the Alexandra Palace.

The Warrington-born prodigy sent a warning shot to established stars by winning the coveted World Youth Championship last November. He kicked on by taking a number of huge scalps on the senior stage.

“I do appreciate what Luke is doing for our sport in a professional manner,” said Humphries. “He is elevating it, he’s doing it for everybody and he’s a credit to darts.

“He’s doing all these things going here, there and everywhere. He’s giving darts a bigger atmosphere. He’s not getting paid to do these things. I’m really proud of how he’s handled all the media attention. If I was 17, I would have been a lot more anxious about it all than he has been.”
