Anthony Joshua and Tyson Fury have become embroiled in a heated verbal spat on social media.
With less than a fortnight until Joshua meets Wladimir Klitschko for the IBF and WBA 'super' heavyweight world title in front of 90,000 people at Wembley Stadium, live on Sky Sports Box Office on April 29, he has responded to a jibe from former title-holder Fury.
