“We were winning on Wednesday and still they were singing about me - I think that will not do our team any favours”
Rafael BenitezChelsea manager
an interview with BBC Radio 5 live
following Chelsea's FA Cup win at the Riverside, Benitez said the decision of the club to give him the title of "interim manager" was a "massive mistake" and that the fans were "wasting their time" in protesting against him.
"We still have 11 games to play in the Premier League, and we have the FA Cup and the Europa League," he continued.
"Everyone knows I will finish my contract at the end of the season.
"So this group of fans, who are singing and creating banners, have to concentrate on supporting the team. The rest of the fans, the majority of fans, know the way to help the team is by supporting the players.
"I'm thinking about my team and my club. I want to win every game. I've tried to explain the way is to support the team in every single game.
"We were winning yesterday and still they were singing. I think that will not do our team any favours."
Benitez has been unpopular with some fans since taking over from Champions League-winning manager Roberto Di Matteo in November.
A section of the club's supporters has been unable to forgive Benitez for his association with Liverpool, or forget the rivalry he formed with then Blues boss Jose Mourinho.
Dan Walker on Benitez interview
The crew and I arrived at the hotel early and - after a few issues with light bulbs - we were all set up and ready for Rafa to arrive. I met him in reception at 14:55 GMT and you could see that all eyes were trained on him and that tongues were starting to wag.
As Liverpool manager, Benitez outwitted Mourinho in the 2005 and 2007 Champions League semi-finals as well as the 2006 FA Cup semi-final. He was also critical towards his current club while in charge at Anfield.
Benitez's cause has not been helped by Chelsea's Premier League form.
They are through to the quarter-finals of the FA Cup and in the last 16 of the Europa League, but they have dropped to fourth in the league behind Tottenham, who are managed by former Blues boss Andre Villas-Boas.
