"I was at Extremadura, Tenerife and Valencia and we had the best statistics in the history of each club," said Benitez.
"I have done it at three clubs. Now I will try and do the same here. It will be very, very difficult I know because the history of this club is so big.
"I have 20 years of my life as a manager yet and I have four more years left on my contract here and that is a lot of time," added Benitez.
"I am very confident and I want to win things. I know there are good teams in Europe and here, but if you don't believe in yourself, it will be impossible."
