Adam Booth believes that Tyson Fury has chosen the wrong time in his career to face David Haye.

The two heavyweights will clash on September 28 in a mouth-watering all-British affair, but Booth, who is Haye's trainer, feels that it is too early for Fury to be challenging the former two-division world champion.

"I'm as confident as I can be that this fight isn't right for Tyson Fury," Booth told Sky Sports News.

"He still has a good career ahead of him but it's just I expect David to be holding his hand high [on the night].

"I really like Tyson Fury, I think he's doing a fantastic job selling himself. I love boxing and I want other people than hardcore fans to see it. Guys like Tyson and David bring those people in. It's great that everyone wants to watch this fight."

Fury overcame Steve Cunningham in his last fight in April, while Haye has not fought since he beat Dereck Chisora 12 months ago.
