Anthony Joshua has been told to shake up his attitude towards Oleksandr Usyk and stop making his rival feel comfortable.
Joshua is aiming to regain his unified crown on August 20 in Saudi Arabia, where he will take to the ring against Usyk for the second time. The British star was heavily criticised for his tactical approach and attitude to the first fight, which has seen him alter a number of factors, including the appointment of new coach Robert Garcia.
The pair have come face-to-face twice during separate press events, where despite sharing intense stare-downs, Joshua and Usyk were respectful towards each other during their brief exchanges. Former cruiserweight champion Johnny Nelson believes Joshua needs to make his opponent feel uneasy, with Usyk tending to box at the peak of his powers when he feels comfortable.
