Francis Ngannou has admitted he was left stunned by Mike Tyson after being trained by the boxing icon for his fight with Tyson Fury last year.

Tyson coached Ngannou, who knocked Fury down before going on to lose via split decision.

Iron Mike is set to come out of retirement on November 15 to battle Paul, with the boxing icon currently training hard.

It will be his first fight in four years, having previously drawn with Roy Jones Jr in their exhibition bout in 2020.

Ngannou knows all about Tyson and the danger the boxing legend can pose.

And the Cameroonian, speaking at a press conference, has admitted he was left stunned after working with the 58-year-old.

“I did train with Mike Tyson, and that was for one fight, my fight against Tyson Fury,” he said.

“Boxing is a completely different sport to mixed martial arts … the application of everything.”
