The Blues won 2-0 at the Riverside Stadium to reach the quarter-finals of the FA Cup but, after the match, Benitez hit out at the executives who decided he would be an 'interim' boss and the supporters who have failed to give him their backing.
"It was two rants really," said Hollins. "Both not very sensible. One against the board, 'I'm not an interim manager, I'm a manager, and this that and the other'.
"Well, we know you're an interim manager and you're doing the job! That's why you said you'd take it to the end of the season.
"You certainly don't criticise the board, perhaps he should have kept it private.”
As for the criticism of the supporters, Hollins added: "They've taken 2-3,000 fans to Middlesbrough on a very cold night.
"He's saying 'you support the team' but they are allowed to say they don't like the manager. Nobody liked me when I was manager of Chelsea too much!
"They used to say 'get rid of him, he's rubbish', but you take it. You don't go back at the supporters with 'what do they know about it'.
"If that is his attitude to the board and the supporters, I don't think he will last very long, maybe the end of the week."
