Tony Bellew and David Haye go to war again in their much-anticipated rematch on Saturday night.

The last fight produced fireworks and a stunning upset, but this time round it’s all about the intrigue.

Was Bellew’s win the first time round a fluke, can Haye rediscover the punching power of old?

So, let’s go through the fight, why it is such a head scratcher and try and predict a winner.

FORM…

CAREERS ON THE LINE…

Haye has vowed to call it a day if he cannot knock Bellew out in spectacular fashion. The two-weight world champion wants to reign supreme again, but he insists anything other than a stunning knockout will force him to end his career.

It means that Haye enters the 32nd fight of his pro career knowing it could be the last. That pressure will surely cause a reaction and Bellew is hoping the cracks in Haye’s confidence will widen.

Much has been made of Haye’s mental state. The likes of Eddie Hearn believe Haye is at his lowest point and for a fighter that relies on a healthy ego, it’s a dangerous scenario.

Bellew has a different view. He thinks Haye still sees him as the ‘mouthy cruiserweight’, someone he should, and will, beat easily.

The numbers are on Haye’s side. 70% of rematches between British heavyweights since 1981 have had a different result in the second fight.

Where Haye might be feeling the pressure, Bellew surely is not. The Liverpudlian has said again and again – this is not his legacy fight.

Bellew has already had his peak moment when he became the world champion at Goodison Park, nothing can top that for Bellew, anything that happens now is a bonus for him.

He’s unburdened in this fight. No one expected him to win the first one, and still no one believes he can repeat the trick. It’s a good position for Bellew to be in, even if a devastating loss could push him into retirement.

Whoever loses this fight, it will be an unfair end to their careers. For Haye, his legacy will be in ruins with successive losses to a ‘blown-up cruiserweight’. For Bellew, his previous win will be chalked off as a farce and his epic foray up to heavyweight will be ridiculed. Not the ending either man deserves, but as Haye says, boxing has a short memory.

STRENGTHS AND WEAKNESSES…

No one gave Bellew a hope in hell when he stepped in the ring 13 months ago, but the Bomber proved everyone wrong. A combination of craft, timing and motivation helped Bellew pull off the upset.

He predicted the outcome perfectly – the fight would be decided by Haye’s body and fitness. The Hayemaker was taken past the fifth round for the first time since 2011, and after a three-year retirement spell, the 36 years old’s body could not take the strain of a 12-round contest.

Bellew will be hoping for the same again. Haye is a year older, coming off the back of another injury and operation. It may be that Haye’s body just cannot take the pressures of boxing anymore.

But, a year out also works against Bellew who thrives as an active fighter. This will be the longest period between fights for Bellew. He’s fought 32 fights in eleven years, averaging about three a year.

Bellew admits himself that is not ideal. Haye will hope the time out will work to his advantage. Haye has tried to rediscover his fire. Legendary coach Ismael Salas has been drafted in to mould him back into shape and Ruben Tabares has been re-hired to look after the conditioning side of his preparations.

Haye is confident the bugs have been ironed out and the heavyweight is likely to have cut some of the muscle that restricted him in the first fight. He certainly looked leaner at the open work-outs. But there are rumours Haye has not stepped up his sparring as much as might be expected for a boxer that looked woefully short of real-time action a year ago.

The power debate is of course, still very relevant. Bellew took what Haye had to throw in the first fight and was able to shake off the bigger shots, but he cannot underestimate the power of the Hayemaker.

Haye can end this fight with one punch, and his legendary 86% knockout record means he remains the heavy favourite even after losing the first contest.

Bellew has promised to come in lighter. He was almost a stone lighter than Haye a year ago and is aiming to come in under the 15st 3lbs 8oz he managed last time.

Not many would argue that Bellew is the more thoughtful boxer, and he will need every ounce of his ring know-how to beat Haye again.

The underdog will look to expose Haye’s footwork and move him around as much as possible before attacking a tired Haye.

THE FIRST TIME ROUND…

Bellew stunned the world when he stopped Haye in the eleventh round of their grudge match in March 2017.

The fight seemed a mismatch on paper, but a measured and energetic performance from Bellew pushed Haye, and his body, to breaking point. And the Hayemaker broke.

A serious Achilles injury in the sixth round blunted Haye’s attacks, but he still survived a further five against Bellew.

Eventually his corner were forced to throw in the towel and hand Bellew one of the biggest upsets in the history of British boxing.

METRO.CO.UK PREDICTION…

Bellew firmly believes he has Haye’s number. Haye’s body seems to be crumbling around him, while Bellew is in peak condition. It’s hard to trust Haye when he says he’s in the best shape of his life. We expect Bellew to do the double over Haye.
