Benitez was reported to be close to quitting the club earlier this week, following a bust up with club owners George Gillett and Tom Hicks.
“I can tell everyone that my commitment to the club is still there,” Benitez told the Mirror. “When I signed the new contract it was because of the staff and because of the players.
“I told everyone I will stay – it was my decision. I’m really pleased here and I’d like to stay for the length of my contract. The fans know this so that’s the most important thing for me.
“The problem here is that rumours go around very, very quickly. Even people who know me wanted to know what was happening. They all ask ‘Are you going? What’s happening?’ I was even surprised myself.
“We had situations similar to this one when we played Real Madrid in the Champions League. It was a surprise then but we won the game.”
