VINCE Cleverly has vowed his son Nathan has several strategies to beat Sergey Kovalev, but his main one is simple, knock him out.

Cleverly believes Nathan can beat the hard-hitting Russian any way he likes.

“Nathan can box inside or outside, and will have a Plan A, B, C, D and F on fight night,” Vince said.

When John David Jackson questioned whether that was too much, Cleverly followed up with: “Of course, everybody is talking about Kovalev’s power, but if anybody is going to get stopped it’ll be Kovalev.

“We have plans from A to F, we can box him long, inside or mid range, but the main plan is K and O.

“Nathan has fantastic stamina, plenty of bottle and he’s going to do the business for Wales.

“He’ll KO Kovalev 100%, I guarantee you that.

“Kovalev just won’t knockout Nathan, he can’t hit what he can’t see. Nathan’s never been down on the canvas.”
