The Spaniard has been brought in to replace Roberto Di Matteo, who was sacked yesterday, and wants immediate success during his caretaker role which runs until the end of the season.
Benitez is targeting a trophy at the least at Stamford Bridge and has vowed to be a hit with the supporters as he looks to win the Blues job permanently.
"My priority was to work in the Premier League, I'm really happy to be here with a top side," said the former Liverpool boss.
"For me the most important thing is I am here because I want to be here. I was looking for the right opportunity, I was looking for a top side who can fight for trophies.
"I don't care about the short-term (deal), what I have in my head is to win every game. We have five trophies to fight for. We will see what happens, in seven months we can win some trophies.
"At this level you are expected to win, do it well, and win trophies. I have a lot of years' experience at this level, and I will do what I have to do to win games.
"I like to do things in the right way for the fans. I am sure they will be happy with a manager with a winning mentality."
