Tyson Fury has some controversial thoughts on how boxing should deal with its doping problem

Tyson Fury has said that doping is a "big problem" in boxing ahead of Saturday's showdown with Wladimir Klitschko.

The British heavyweight says that the only way to make things "fully fair" for the sport is to allow everybody to use performance-enhancing drugs. Speaking to BBC Radio 5 live, Fury said: "I can look at a man and tell you if he's full of drugs by one glance at his body with his top off. Boxing has got a big problem with drugs. But it doesn't bother me because at the end of the day it's about determination over drugs." The 27-year-old then laid down a controversial plan on how to level the playing field: "I think being in a democratic world means we have to be open to different things," said Fury. "Why don't they make drugs totally legal in sports and then it would be fully fair?" "If the governing bodies want to do that, it will be a bit fairer. You can't tell me that 99% of these sportspeople ain't taking drugs if they've got bodies like Greek gods. "If a man wants to pump himself full of drugs it's only shortening his life isn't it? When you're pumping yourself full of drugs it's putting pressure on your heart, your liver, your lungs, your kidneys. "You're on a one-way ticket to a heart attack so that's why you see a lot of these body-builders and weightlifters having heart attacks young because they're pumped up so much and the heart can't take the pressure."
