The Brit was in bullish mood when asked about Fury, who he is expected to face next year in two blockbuster heavyweight showdowns after both sides agreed on the finances last month.
Joshua, who holds the WBA, WBO and IBF world titles, is ranked below Fury after the Manchester giant demolished Deontay Wilder in seven brutal rounds back in February to take the No 1 spot in the division.
But Joshua acted as if he is yet to be convinced that Fury, also a two-time world champion, even belongs in the top bracket as he appeared to accuse him of having a padded record.
Speaking about Fury’s armoury during a live Q&A session with Sky Sports, Joshua said: ‘If the sport is lacking so much talent, it just shows all you need is feints and a bit of movement to be classed as one of the all-time greats of this generation right?’
If it was the beginning of a campaign to get under Fury’s skin then what came next will have almost certainly tested his rival, not least cause an eyebrow to raise.
