Knighton, but the point stands. He wasn't the manager at the time so wouldn't have been privy to any of it. Also, he never even said that Norris 'bribed' other chairmen.
He was known to have a very bitter relationship with Norris though, probably exacerbated by Norris sacking him. Another reason why he might try and get back at him and make spurious claims (even though he didn't)
Oh and his autobiography has been shown to have many glaring factual inaccuracies, it being noted that his comments on Norris cannot be taken with any degree of authenticity.
