And the 31-year-old 2004 Athens Olympic silver medalist declared Fury is the best heavyweight in the world today.
“I think, out of all the heavyweights, in my opinion, I think he’s the best one,” Khan told the Alan Brazil Sports Breakfast.
“I think he will beat them all.”
When quizzed directly about whether Fury would be able to overcome Joshua, the Bolton man said: “I think he would because he has that unorthodox boxing style.
“He has power, he has good speed, good movement. [He’s] huge and very long.
“He’s had two fights since he’s been back, had a long layoff, he wants to fight Wilder.
“If he beats Wilder, then you have to put him right at the top of the chain.
“I mean there’s a lot of fighters out there, for example Joshua people are saying, that don’t want to fight Wilder.
“Wilder’s one of those type of fighters who will give anyone problems.
“To have Tyson Fury saying: ‘I want to fight him.’ Coming off a couple of years lay-off. It’s some confidence.
“I think he can pull it off as well.”
