Ammon News - Anthony Joshua has been warned about the difficulties of preparing for Tyson Fury, with few heavyweights able to imitate his British rival, who can ruin a trainer's tactics at any moment in their world title fight.

Tyson Fury tore up a British rival's tactics on two occasions, while a former sparring partner has also warned Anthony Joshua about his 'impossible' task...

Joshua is expected to face Fury in an undisputed world title fight this year, with their promotional teams currently finalising terms for a blockbuster battle that will decide the sport's No 1 heavyweight.

But how can Joshua find a way to topple the unbeaten Fury, with no successful tactics to follow or similar heavyweights to spar?

Don Charles had the task of plotting Fury's downfall in 2011 and 2014, but his fighter Derek Chisora was left bemused and bloodied on both occasions.

When I was doing my study, to research Tyson Fury's weaknesses and his strengths, his weaknesses were that he's open to the overhand right. But that was early on in his career.

We were working daily to get inside and be able to bowl the overhand right. It's not even a straight right. Like a bowler, a looping overhand right.

Even back then, when he was still coming through, he was able to avoid being hit with that shot. He did get hit with it a couple of times. He was riding the shot, so it didn't have the full effect on him.

The second time around, we went away and won the European title. I was that convinced that a fitter Derek Chisora would be able to put enough pressure on Tyson Fury and be able to be victorious.

I would bet my house on it, that's how sure I was. Not only myself as a trainer, Derek Chisora promised the press, 'You're going to see the best knockout ever,' he was that sure.

As soon as the bell rung, he came out in a southpaw style. That effects your game-plan in a major way. We haven't trained for a southpaw.

I had anticipated that he may do something like that. The first time he ever boxed southpaw was against Martin Rogan and we did employ a southpaw (in sparring) during our preparation.

When it comes to Fury, you're looking at a 6'9" southpaw, very unorthodox and incredible lateral movement, incredible ring IQ.

Even if you ask me today, with all my experience, how do you prepare to beat this guy? It's almost like any game-plan you come up with, he has the ability to change to win the fight. That's the problem for any trainer, training somebody to go and beat Fury.

Even after plan A to Z, I'm not exaggerating, it's still not going to be enough. There aren't boxers like that where they adjust during the fight. There are only a few fighters in boxing history who present that kind of attribute.

David Allen has sparred with some of the world's top heavyweights, including numerous sessions with Fury, and questioned whether Joshua can find anyone to replicate an unpredictable opponent.

It's so difficult, because he can do everything. We've seen him in with two elite heavyweights, two world heavyweight champions. In Wladimir Klitschko, we saw him on the back foot, boxing, moving, being awkward like we know he can.

In the Deontay Wilder rematch, he showed us he can come forward, hands high, big punching power, and he can get rid of you. He can beat you up.

The difficult thing is - he can do everything and anything. Whatever you want to do, he's got the answer.

Tyson is a headache for anyone. I wouldn't want to be the man putting a plan together against someone like him.

I wouldn't want to go southpaw against Anthony Joshua, if I was Tyson Fury. We saw with Charles Martin, that Joshua deals well with southpaws and that straight right hand is one of his best punches.

Tyson is a headache for anyone. I wouldn't want to be the man putting a plan together against someone like him.

I think it's nigh on impossible, to be honest.

They need to be tough. The biggest, toughest men you can find. Anthony Joshua doesn't mess about, so you have to be tough to hang in there.

It's great, if you can find a world-class mover, but how many are in the heavyweight division right now? It's a very difficult job, to be honest.
