The ex-Liverpool boss has not been welcomed by the majority of the Chelsea fans following his appointment after the swift dismissal of Roberto Di Matteo, who clinched the FA Cup and Champions League trophy with the West London club last season.
"I cannot change the perception people have of me because I was successful at Liverpool against Chelsea," Benitez told The Mirror. "I thought when I came that if I carried on winning games here, it would get easier, but if you cannot win all the time.
"I understand that sometimes the fans get a little bit frustrated and I am frustrated too, but at any club, whatever its circumstances, there are always going to be people who do not agree with you.
"In football in England, you have 60 million managers. In Spain, there are 40 million managers. Everyone has an opinion. You have to accept that this is normal. Especially now, in this society, everything is so quick."
Chelsea currently sit in third place in the Premier League table, just one point ahead of Tottenham Hotspur.
