Possible it's not as simple as him either saying it or not, but a comment that could be (possibly deliberately) misconstrued, asking a player to cut out the monkey-business, 'softly softly catchey monkey' in relation to them surrounding the ref or something - or even something that Clattenburg claims was misheard. Imagine it'll be another tedious, drawn out saga about intent and meaning rather than a black and white did he say it or not.
