Benitez's Newcastle future is still unclear, with the 59-year-old's three-year deal set to expire on June 30 and a contract extension yet to be finalised.
Asked how long he planned to continue in management, Benitez said: "Yesterday I was talking with a friend - 11 years. Eleven years as a manager, that's fine. You can see Roy Hodgson is still there.
"I like to manage teams, I like to coach players, so I'm happy with that. Always I say we are forward-thinking. My staff, they are young people and we are always thinking about how to improve things.
"Yesterday, we had a meeting and we were talking about cameras for the training ground, to record from different points and then have the possibility to watch from different angles, things like that, so we are always trying to use the technology, we are trying to be up-to-date, all these things."
