These two Sheffield lads get their kicks from an entirely different sport.
And those in the know reckon they have the potential to go all the way in a sport where, like World Cup footballers, the best can earn millions.
Coaches and judges believe kick-boxers Shane Beard and Alex Mackenzie have the stuff which can only mean a bright future in one of the roughest, toughest, not to mention fastest growing, spectator sports on earth - cage fighting.
The stuff they have may surprise you - especially if you thought the main requirements for a good kick-boxing cage fighter are a tough look and attitude.
"In this sport it's very rarely the big, rough-looking, mouthy bloke who wins," says Paul Powers who instructs the lads at Self Defence UK of Malin Bridge, Sheffield.
"Outside the ring these two lads are among the nicest people you would ever meet. They are polite, thoughtful and sensitive.
"The lads are so quiet you'd never guess in a million years that inside the ring they are top notch fighters."
Shane, aged 18, a trainee chef from Parson Cross, has been kick-boxing for a couple of years and when he took part in his first full contact match in Doncaster the packed crowd was left as stunned as his opponent.
Paul said: "He was taking on a fighter who was at least 14lbs heavier but, after two hard-fought rounds, he managed to knock him out with a stunning hand and leg combination."
Alex, 25, a personal trainer from Stannington, fought his first mixed martial arts semi-professional fight against a Newcastle man who, again, was at least 14lbs heavier.
Paul said: "After a tough start to the fight, Alex managed to knock his opponent out after three minutes of the first round."
Afterwards Paul was approached by scouts asking if Alex would fight at the Doncaster Dome in a full contact match at professional level, and if Shane would fight at the same event at semi-pro level.
"The lads have come so far it's remarkable," Paul marvelled. "Scouts representing promoters of cage boxing, which will be bigger than boxing within a few years, would like them to fight at their events.
"That's unusual for a sport where most fighters reach their prime in their 30s.
"Cage boxing means big money these days with some of the stars in the US even becoming multi-milionaires.
"I see a very bright future for these Sheffield fighters and, as their instructor, I am very proud of both the lads."
