Chelsea supporters will boo interim boss Rafael Benitez until the end of the season, say a fans' group, reports BBC Sport.
"We want the powers-that-be to realise we didn't want him", said Trizia Fiorellino, chair of Chelsea Supporters' Group.
David Johnstone, spokesman for the CFC UK Fanzine says booing "doesn't help the team."
Former Liverpool manager Benitez took over from Roberto Di Matteo, who was sacked after the team's Champions League exit.
Following Sunday's 0-0 draw with Manchester City, Benitez said that he wanted to change the perception of the fans by winning games.
But Fiorellino said: "The strength of feeling surprised even those in charge . It was quite venomous right at the beginning.
"The fans don't expect to pick and choose the managers but it was pretty evident there were only two people that were not acceptable in this case - Benitez and Avram Grant.
"It was almost as if the board and the owner were trying to send a message to the fans to say 'we run this club, not you - you have no say.'
"Benitez is not popular and I think he will remain unpopular throughout his reign."
