Norwich City majority shareholder Delia Smith says negative supporters are harming the club.
The Canaries are 14th in The Championship table with seven wins from their opening 18 matches.
"To have that negativity there, all the good supporters get overwhelmed by the 'boo-boys' with the loudest voices," said Smith.
She was speaking after the club's annual general meeting at Carrow Road.
Smith and her husband Michael Wynn-Jones have been majority shareholders at Norwich since 1995, but will be joined as co-owners by US businessman Mark Attanasio when the deal is rubber-stamped in the coming days.
