DANIEL DUBOIS wrecked Anthony Joshua’s hopes of a dream career ending with a right-hander for the ages.

Dynamite Dan detonated a fifth-round shot — after dropping AJ three times in the previous four rounds — to keep his IBF world title and ruin AJ’s dream spring mega-fight with Tyson Fury.

They were five of the most brilliant rounds imaginable.

Joshua, 34 was cooked from the very start, dazed and confused, bouncing about the ring and then sticking his tongue out and trying to showboat. But it wasn’t funny — and it was potentially the end of an era.

It was also the crowning of 27-year-old Dubois as bona fide world champion and a menace for all of the other heavyweights to now fear.

There was no brotherly glove lost between the two Londoners.

And there was none on show when Liam Gallagher appeared to do a three-song set without newly reunited Noel — so this Idler’s Dream was dashed and it was back to work.

The last sprinkle of showbiz was a rerun of the Guy ­Ritchie-directed promo that launched the mega-money 96,000 Wembley sell-out.

Dubois played the role of a torture victim, strapped into a freezing bath where bloodthirsty gangsters electrocute him with jump leads.

But now he was really going in the deep end to see sparks fly — lock stock and two smoking biceps.

The biggest headline of the fight-week build-up was Dubois’ new trainer Don Charles vanishing for the most critical days of Dynamite Dan’s career.

Thankfully Charles did appear, entering the ring with his charge with dad perched on the outside of the red corner.

But when AJ emerged second — a ­baffling move considering he was the challenger — it was to the Godfather theme tune.

It seemed like Dubois needed back-up against the family.

But he made a mockery of that plot from the off.

After the 27-year-old took control of the fight from the very first bell with a great jab, he made the older man look like the challenger he was — the man who should have been made to come first and wait in the ropes.

Then — with 16 seconds of the opening round left — Dubois looked right over to his father and it looked like he was having daddy issues.

But he then unleashed a right hand that almost knocked AJ spark out.

Joshua collapsed to the floor and looked utterly doomed.

It was a miracle he rose again and made the second on dodgy legs.

The second instalment didn’t start any better for Joshua either.

But Joshua scored with an uppercut that suggested he was easing into the fight.

Then Dubois threw a left hook that robbed AJ of all of his senses — and a count from outside the ring started.

Ref Marcus McDonnell ignored that call.

Then Dubois battered him more and more and he collapsed into the ropes and was hauled up for a standing eight count.

As soon as the fourth started Joshua was decked and counted again — but he moaned he had merely slipped.

Even so, that was three floorings in the opening four rounds. A slaughter.
