It takes a lot of courage to stand up to someone like Anthony Joshua, especially if you're trying to get a reaction out of them.As you'd expect, though, this isn't enough to put off a group of likely drunk Brits from having a go.A clip has surfaced on the internet of a group of Tyson Fury fans shouting at Joshua as he walks through a resort in Marbella surrounded by bodyguards... as if AJ wasn't scary enough by himself.The chants from the Fury fans went along the lines of: "There's only one Tyson Fury!"The fans of the Gypsy King continued to chant this line over and over again, leading to Joshua looking at the group and flipping the bird at them in response.Luckily for the Fury fans, Joshua seemed to be joking around, as he can be seen laughing while addressing the rowdy group of rival supporters.Towards the end of the clip, one member of the group can even be heard telling Joshua: "Come here!"

Sounds like someone's had a bit too much to drink. Inviting AJ and a group of bodyguards over to fight doesn't seem like something a sensible person would do... although it's more than likely he was joking around and having some banter with the champ.

This sort of thing is bound to happen even more in the run up to what could be the biggest all-British boxing fight in history.

Both Joshua and Fury have apparently agreed financial terms to fight twice in 2021, with the purse split 50/50 for the first one, and 60/40 for the second, with the winner of the first bout receiving the bigger slice. 

Before the fight can take place, Joshua needs to defend his IBF title against mandatory challenger Kubrat Pulev, which will most likely take place in November, virus permitting.

Fury is also signed up for one more fight against Deontay Wilder due to a rematch clause, which will probably happen in December.

On top of that, both Fury and AJ have another mandatory title defence lined up in 2021, though, it is rumoured that they will ignore these so that they can fight each other as soon as possible.

Whatever happens, it's clear to see that emotions are already running high between fans of either camp, so it's easy to imagine what the atmosphere will be like even closer to the event.
