Stipe Miocic has hit back at Anthony Joshua after *that* Instagram comment

Anthony Joshua is not usually one to engage in trash talk.

But 'AJ' simply couldn't resist the opportunity to take a shot at the UFC heavyweight champion when Stipe Miocic officially called him out for a fight on the undercard of the upcoming Conor McGregor vs. Floyd Mayweather spectacle. Eager for the payday that would accompany a fight against Joshua and confident of his ability to hang with the reigning IBF, IBO and WBA heavyweight champion, Miocic took to social media to make his availability known. https://twitter.com/stipemiocicufc/status/875129564086841346?ref_src=twsrc%5Etfw&ref_url=https%3A%2F%2Fwww.joe.co.uk%2Fsport%2Fanthony-joshua-had-a-fantastic-response-to-approach-for-fight-on-mayweather-vs-mcgregor-card-129818 Joshua was made aware of the offer via a post on the Instagram page, HeavyweightBoxingUK and took the opportunity to respond with a lighthearted dig. 'AJ' commented under the post with a catchphrase made famous by McGregor as he asked: "Who the fooook is that guy?" https://twitter.com/DarrMurphy/status/875472169127604224?ref_src=twsrc%5Etfw&ref_url=https%3A%2F%2Fwww.joe.co.uk%2Fsport%2Fanthony-joshua-had-a-fantastic-response-to-approach-for-fight-on-mayweather-vs-mcgregor-card-129818 Well Miocic has not taken too kindly to that little jibe as he hit back at the London 2012 gold medallist late on Monday evening. https://twitter.com/stipemiocicufc/status/876920226444709889 Miocic is presumably suggesting that the sidelined Tyson Fury is in fact the best heavyweight boxer in the United Kingdom, not Joshua. Fury unsurprisingly agrees with the UFC star, as the controversial boxer continues to ridicule 'AJ' ahead of their inevitable all-British showdown, which will likely take place at some stage in 2018.
