The best approach to all rumours from an official club pov (BUT you MUST apply it on every occasion without wavering or it can come back to bite your bottom):
"It is our/my policy to neither confirm nor deny (insert rumour)". It's a firewall that leaves the questioner nowhere to go. Especially effective at killing speculation if applied time and again to the same audience/interviewer.
Yeah but that’s boring. I want Mike Hine’s input on whether we’ll sign a striker from the Scottish fourth tier.
