Believed to be the world's youngest cage fighter, Alfie Williams is putting us all to shame by having achieved more than any of us probably will in our lifetimes - by the tender age of nine.
Yup, while most of us can't even commit to a light jog every week, Alfie is determined to one day become a world champion MMA star like Conor McGregor. Having won his first fight in just 22 seconds, the youngster has since emerged triumphant from 15 out of 20 bouts.
