However, Joshua is widely considered to be a nightmare matchup for Paul.Given the massive size and power difference between the two, many believe Paul will struggle to put any kind of pressure on Joshua. Unsurprisingly, Paul is gearing up to face Joshua by training with heavyweight sparring partners, and it appears he hasn't been struggling to deal with their size or punching power.In a recent interview, Paul got honest about his training process with heavyweight opponents and said:"You know, it's not that bad, to be honest, so far in camp. I'm moving so much that they're not being able to load up their punches. So they're getting frustrated and falling on the ground trying to chase me. To be honest, I didn't even feel any of the punches so far. We'll see, I think we're bringing in some tougher guys... Still got some weeks to go."Jake Paul issues a bold prediction for Anthony Joshua boxing matchJake Paul believes he can push Anthony Joshua to his limits in the squared circle.

You know, I beat him in laser tag when we first met in Dubai. He didn’t see me coming. I was popping around the corners, shooting him nonstop, eliminating him multiple times. That’s because I’m tricky. I’m sneaky, and I’m fast. It’s going to be a long night for him. Long night. Long night."
