Jake Paul has fans fearing the worst having released new footage from his training camp.

Paul is set to face heavyweight legend Mike Tyson in a huge fight on November 15, and he has bulked up significantly to reach heavyweight to meet the icon.

It will be the Problem Child’s first appearance at the new weight, as he bids to match the power of the 58-year-old, that he clearly still carries on the pads despite his physical condition.

He has today posted footage of himself, just 41 days out from the contest, going through the motions in a sparring session.

Paul can be seen being the aggressor and on the front foot, unloading a barrage of punches on his sparring partner who barely throws back.

The American clearly carries power, but fans are surprised by Paul’s ‘heavy’ looking appearance, and what this means for his fight with Tyson.

A user responded: “He looks really different. He looks heavy as f***k and really slow.”

Another wrote: “Why does Jake look slow and sluggish? He’s in trouble.”

One fan agreed: “Dude looks slow and sloppy what happened to him?”

Others made predictions on the back of seeing the footage, with one writing: “Bro leads with his head way too much.

“With hands down too, he’s going to put to sleep like that.”

Another concurred, adding: “Jake Paul going to get slept fighting like that.”

One even joked: “Sparring and dude didn’t throw a punch lol. Pretty sure Tyson will throw punches back.”

A user added: “Better do better than that. Mike Tyson’s gonna take your head off.”

But others were optimistic, with his ex-trainer BJ Flores arguing: “That jab to the body sets up a heavy right hand all day.

“Great punch selection. Insane pace for a heavyweight.”

One even concluded: “I’ve seen enough he’s ready for Oleksandr Usyk.”

Time will tell how he will fare but Paul is extremely confident of beating his ageing rival.

He is training extremely hard for the event, which will be a sanctioned professional bout despite concerns for his rival’s health.

Tyson has equally tried to prove his fitness with training footage, but has only posted much smaller montages.

The former undisputed champion has even admitted he is struggling with his own sparring, being left finding it hard to walk after several rounds.

Paul will be favourite to win on the night despite his rival’s experience, and will be looking to avoid an early KO, which Tyson clearly still possesses the tools to deliver.
