Mike Tyson smashes sparring partner through the ropes with vicious left hook ahead of Jake Paul showdown

Mike Tyson looks to be firing on all cylinders judging from his latest sparring footage.

'Iron Mike' is set to square off with Jake Paul next month at the AT&T Stadium in Arlington, Texas - and is leaving no stone unturned in camp.

Tyson recently celebrated his 58th birthday but proved age is just a number by smashing his sparring partner through the ropes.

The former undisputed heavyweight champion uploaded a clip of him sinking his adversary with a vicious left hook.

And captioned the video: "I'm just getting started."

As Tyson connected his coach Rafael Cordeiro could be heard shouting 'nice left hook' before calling a halt to the sparring and telling his student.

"That is good for today," said Cordeiro as another coach took off his headguard.

"Are you sure?" shouted Tyson. "You're not f***ing with me right?

"Are you sure? I've got a lot in me."

The video will breed confidence in Tyson fans, who expressed their concerns after 'The Baddest Man on the Planet' admitted he was struggling to walk after a six-round sparring session last month.

Speaking to in September, he said: “It’s hard to walk right now.

“But two months from now I’m going to be perfect. The fight is won in the gym.
