Ngannou controversially lost that bout on points – but if Friday’s bout with Anthony Joshua maps out the same way, AJ might not be so lucky with the verdict.

The Cameroon-born superstar, 37, was again in Saudi Arabia as he repeated the right-leg-back, right-fist-forward swing during his session with trainer Dewey Cooper.

Six months earlier the superhero move surprised the world of boxing in the final round of his first-ever pro boxing fight against the out-of-sorts Gypsy King.

And this time it had fans wondering if Joshua might face the same in another Riyadh blockbuster.

All-time great Mike Tyson, who trained Ngannou for the Fury bout, revealed the Superman punch was his idea.

But it couldn’t help the MMA legend to a Hollywood ending as the unbeaten Mancunian beat him on a contentious split decision.

One judge gave it 95-94 to Ngannou but the other two  but the other two scored the absorbing contest 95-94 and 96-93 in Fury’s favour.

The former UFC heavyweight king will take on AJ a day before the usual scheduling for a weekend because the Saudi Arabian Grand Prix is on Saturday in Jeddah.

The undercard includes Joe Joyce’s two-time conqueror Zhilei Zhang clashing with Joseph Parker – Deontay Wilder’s impressive vanquisher three months ago.

But the main draw is Fury vs Ngannou.

The outsider has famously power-packed thighs that might help propel him up, up and away to a Superman punch.

But he joked withSunsport that his “legs are too skinny” and “needs weights”.

he’ll certainly be the bee’s knees in a second major sport if he KOs AJ!
