Anthony Joshua's last opponent Otto Wallin believes the Briton will get the job done against Francis Ngannou on Friday night.
Joshua and Ngannou fight live on DAZN PPV, in Saudi Arabia, with one eye on a potential world title fight in the future.
'AJ' showed signs of his best against Wallin last December, beating the Swede in a dominant five-round win in Saudi Arabia.
Wallin, whose only other professional loss came via unanimous decision against Tyson Fury in 2019, says he admires former UFC champion Ngannou, but does not see him causing an upset.
"A guy like Ngannou, who is that big and who hits that hard, always has a chance, but I'm having a hard time seeing him beating Joshua," Wallin told Reuters.
"Since boxing against Joshua, I have a lot of respect for him. He was good – big, strong, long reach, he countered well.
"There were some concrete things that he did well that I don't want to talk about, I want to keep them to myself, but there are other concrete things that I need to practice and do better, and that's what I'm working on now.
"It's going to be exciting to see what happens on Friday - we're going to see how good Ngannou really is."
