Frank Warren, co-promoter of WBC heavyweight champion Tyson Fury, is not expecting a fire-fight when Anthony Joshua steps in the ring with Kubrat Pulev.
Joshua will defend the WBO, IBF, IBO, WBA heavyweight titles against Pulev on Saturday night at SSE Arena at Wembley.
At Friday's official weigh-in, the two boxers were pulled apart after trading heated words.
Some are expecting an action-packed fight - but not Warren.
He expects Joshua to replicate the same fight strategy that was used in his rematch with Andy Ruiz in December 2019.
In that contest, Joshua played it safe by boxing at a distance, moving often and avoiding scenarios where he was trading punches at close range - and those tactics allowed him to win a lopsided twelve round unanimous decision.
"Anthony Joshua showing vulnerability has made his fights even more interesting. Now even more want to tune to see if he will get his whiskers tested like Andy Ruiz did last year. But I believe we will see a repeat of the performance from him that he delivered against Ruiz in the rematch," Warren told Daily Mail.
"And I say that as a big fan of Joshua, no matter what the preconception may be about that. He's a British fighter so, of course, I want him to be successful – just not against Tyson Fury. After getting floored so many times against the Mexican-American in the first fight, Joshua went on the back foot in Saudi Arabia and boxed his way to an easy points win.
"I think we will see a similar performance to that against Kubrat Pulev tonight. Why? Because there is simply too much to lose for him if he suffered a shock second defeat in his career. That is because there is a huge clash with Fury waiting for next year."
Earlier this week, Fury made it clear that he wasn't planning to be ringside for Joshua-Pulev.
Should Joshua win, he will be in line to face Fury in a two-fight series in 2021. The two boxers have already reached an agreement in principle on the financial terms.
"Fury won't be ringside tonight at Wembley Arena because he won't be part of the Eddie Hearn show. This is about the fighters and not the promoters so lets just get the deal done and then do the promotion. We will see if Joshua really wants the fight if he wins tonight. For the fight to happen the two fighters must be happy and all those contracted to both men," Warren said.
"If the two fighters really want it then terms will get agreed and everyone else will fall in line. It is a heavyweight fight that has to happen. But first, we cannot rule out Pulev throwing a massive spanner in the works. He's 39, not at the top of his game but he will have in his mind to land his big bombs. He's been up there in the world rankings for god knows how long. This is his chance so he will give it a good go."
