Francis Ngannou stuns boxing with insane physique ahead of Anthony Johsua fight

Ex-UFC heavyweight champion Francis Ngannou has left jaws on the floor after showing off his jacked rig ahead of a boxing showdown.

Shocked boxing fans declared there is no way Anthony Joshua can knock out Francis Ngannou – after the Cameroonian showed off his insane physique.

The former UFC heavyweight champ steps into the boxing ring for a second time next month when he takes on AJ in Saudi Arabia, The Sun reports.

After massively scaring Tyson Fury in October, he is confident of causing plenty of problems for Joshua.

And supporters are inclined to agree following the veteran’s latest Instagram post.

Hulking Ngannou, 37, shared a video to his 6.6 million followers of his trainer repeatedly slamming a weighted wall ball against his set of rock-solid abs in the gym.

The fighter remains unmoved in his training shorts with a towel around his neck and headphones on.

Ngannou captioned the clip: “My face when they said that I don’t belong in boxing. Not born different, built different.”

And that prompted a wave of responses with his followers feeling ominous for Joshua’s chances on March 8.

One said: “AJ ain’t knocking that thing out I’m sorry.”

Another wrote: “Only way you are beating this man is on points.”

A third added: “AJ has a mega problem not solvable.”

A fourth typed: “AJ is in trouble.”

A fifth commented: “Legend says they had to add cement on the ball cause he was breaking them all.”

More fans echoed the same sentiment that Joshua is in big trouble when the fight rolls around while others said they couldn’t be paid enough to step foot in the ring with him.

However, AJ fans sent a similar chilling warning to Ngannou after he posted his own content from inside his training camp.

Supporters do not have to wait long before the first bell in two-and-a-half weeks’ time.

And they will have the choice to catch the blockbuster pay-per-view event on Fox Sports or Kayo.
