WBC heavyweight champion Deontay Wilder does not expect an easy fight when he steps in the ring with Tyson Fury in a potential fall showdown.
Fury made his return from a two-and-a-half-year absence against Sefer Seferi in June, the Briton comfortably recording a fifth-round victory in Manchester.
It was Fury's first fight since beating Wladimir Klitschko in November 2015 and represented the first step in his attempts to regain his world titles.
Fury returns on Saturday night in Belfast, when he face world title challenger Francesco Pianeta.
Wilder will be seated at ringside.
"I must admit, in all honesty I feel Fury will be a tough fight for me and a much tougher fight than people think too. Fury is one of the best and I just want the best to fight the best," Wilder stated.
"It’s going to be a great night I’m really look forward to Belfast."
While Fury has been out of contention, Anthony Joshua and Wilder have come to the fore, the pair holding the heavyweight straps Fury is so keen on winning back.
The 29-year-old is confident he will be on top of the world once again and told talkSPORT: "I will beat them [Joshua and Wilder] both twice. Just to show them how s*** they really are. I will beat them senseless.
"People may listen to this and say this man's a lunatic, he's been out for a year. But I'm the greatest boxer that's ever lived in the heavyweight division."
Fury rejected criticism that he did not take his return fight seriously and has no intention of changing his approach to future bouts.
"I'm an entertainer," he added. "I've been told to take this fight serious and stop all the razzmatazz, but you know what? I can't. I'm a natural showman.
"If I wanna put my hands down in the fight and play to the crowd and have a look and chat to a good looking woman at ringside, I will. It's the Tyson Fury show and I do what I want."
