Eddie Hearn, promoter for IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua, believes his boxer will "demolish" WBC champion Tyson Fury in their highly anticipated unification clash.

The two sides are zeroing in on a date of August 14 in Saudi Arabia.

The agreed-upon date will prevent a conflict with the Tokyo Olympic games - which ends on August 8. And it also prevents a conflict for Joshua's head trainer Rob McCracken, who also coaches Team GB's boxing team.

Joshua and Fury have been trading plenty of verbal jabs in the last few months.

During most pre-fight builds, Joshua stays composed in a very respectable shell and rarely talks trash.

Hearn expects a very vocal version of Joshua in the build to the Fury fight.

He believes the 2012 Olympic gold medal winner will be extremely fired up for this particular contest.

"You will get a different AJ in this build-up. He's excited because he's never really, apart from the Dillian Whyte fight, been in a trash-talk environment. He will enjoy it," Hearn told Sky Sports.

"AJ has got the bit between his teeth, goading him a bit. I'm sure these two DM each other, goading each other. I get DMs from Fury - sometimes pleasant, sometimes unpleasant!

"When the announcement comes and the press conferences start, the pleasantries will go away and it will become personal. It doesn't matter who respects who. Both sides are desperate to win because this is everything. There are no fun and games. It's 'them and us'. AJ will go to war with Fury. He has plans to absolutely demolish him. That's what I believe he will do. In the meantime we will go through the build-up, which will be a lot of fun, before the biggest event of 2021."
