Benitez hopes to guide Chelsea back into the Champions League and to Europa League final victory before departing this summer at the end of his short-term deal.
"It's always a little bit sad when you have to go, but it's part of our job now," Benitez said.
"I can see the experience at Chelsea as a positive experience. They are a top side and a very good group of players. It's been a great experience."
Benitez has suggested that he expects his former arch-rival Jose Mourinho to return to Chelsea as his successor.
The former Valencia and Liverpool boss was Mourinho's successor at Inter Milan, inheriting an ageing team, whereas Chelsea's squad is full of potential - in the form of David Luiz, Oscar, Eden Hazard, Juan Mata and others.
Benitez was asked if he would volunteer help to the new manager.
"Good question. You think that he will ask me?" Benitez said.
"That's something you have to ask the new manager."
Benitez will instead concentrate on the task in hand, which continues against Tottenham in the Barclays Premier League Wednesday night - when the Blues can seal a Champions League qualifying spot - and also features next week's Europa League final against Benfica.
"My job is to do what I have to do this year," he said.
"My target is to finish in the top four, top three. Now we're in the [Europa League] final and trying to win the final. That's it.
"That is the situation and we have to deal with that. We will try to keep doing a professional job with integrity until the end."
Benitez hopes to add to his haul of silverware in a successful conclusion to the season and made reference to comments made by Manchester United boss Sir Alex Ferguson.
The Spaniard said: "I don't want to talk about too much about my CV, because we know what people will say, but the reality is that I have won all the trophies you can win in football at club level.
"Still you work hard, trying to do well."
Qualifying for the Champions League was always the priority after he was appointed successor to Roberto Di Matteo and a return to Europe's elite competition will all-but be assured with victory over Spurs tomorrow.
Spurs are managed by another former Chelsea boss, Andre Villas-Boas.
Benitez would not be too drawn on a manager about whom he knows little.
"I don't know him personally and I will not have opinion if I don't know him or talk to him," Benitez said.
"He is doing a good job for Tottenham and is a young manager who is growing. That's it."
Villas-Boas had hoped to be a long-term solution as Chelsea boss, but complained of being undermined by senior players and departed.
Benitez was asked if Chelsea should have continuity, with owner Roman Abramovich to make his 10th managerial appointment in 10 years this summer.
"[It is] not my job to give an opinion on these things," Benitez said.
"As a manager you want to be 20 years in a job and if you can build something it will be easier. But it's not my job to criticise anyone.
"In England stability was a key factor in the success for some teams. In Europe it's not common and in England it's more difficult too.
