Benitez confirmed he would be leaving Chelsea in the summer as part of an impassioned monologue following the holders' 2-0 FA Cup win at Middlesbrough on Wednesday night, which set up a quarter-final tie with Manchester United.
The criticism sparked suggestions his tenure in caretaker charge could end early, but Benitez insists his relationship with Chelsea owner Roman Abramovich and the playing squad is strong.
"My relationship with the owner is really good," Benitez told BBC's Football Focus.
"Every time I talk to Abramovich about football, I enjoy (it).
"I know that he wants to win. I'm here because he wants to win and I will try to do my best until the last day.
"The relationship is fine. I don't have any problem with anyone.
"I have conversations with Michael Emenalo, the technical director, every single day. He watches the training sessions, we talk about football and when I meet Roman Abramovich, we talk about football.
"We talk like normal people. We share a passion for football."
