Everyone in heavyweight boxing knows who the real champion is, says Tyson Fury

Tyson Fury insists he would not be attempting a comeback if he thought he was unable to defeat world heavyweight champion and British rival Anthony Joshua.

Personal issues and legal troubles have kept Fury out of the ring since November 2015, when he defeated Wladimir Klitschko for the WBA, IBF and WBO titles - which are all now in Joshua's possession.
