LONDON — The managers of Norwich and Derby are confident their clubs will be cleared of any wrongdoing in the match-fixing investigation into their League Championship meeting earlier this month.

England's Football Association is investigating irregular betting patterns in Asia during Derby's 2-1 victory on Oct. 4.

"There's certainly nothing for us to hide," Derby manager Paul Jewell said. "It's comical. ... It's something that as far as I'm aware is nonsense. It's just such a big surprise that Derby went down to 10 men and won a game."

Derby goalkeeper Roy Carroll was sent off five minutes into the second half. Sammy Clingan converted the penalty to make the score 1-1 after Rob Hulse's 26th-minute goal for Derby, and Nathan Ellington scored the deciding goal for Derby five minutes from the end at Carrow Road.

Norwich manager Glenn Roeder said his club has nothing to hide.

"I would be 100 percent certain there is no one at Norwich City that's involved," Roeder said.

"Anything like this is not good for the game, not good for any sport," he added. "If professional sport isn't clean, what is the point of being involved in it? But it's certainly unsavory and not welcome anywhere in any sport."

FA chairman David Triesman said he believes English soccer is generally not susceptible to corruption.

"I think we've got a very clean sport," Triesman told The Associated Press.
