The Spaniard was named as interim boss until the end of the season at Stamford Bridge, following the sacking of Roberto Di Matteo in November.
Benitez says he will consider his options in the summer, but concedes that he would be in favour of an extended stay with the Blues.
"A lot of doors can be opened but the main one is this one here," Benitez told The Times. "I don't want to enter this debate at the moment, as the priority for me is to do really well and to win trophies for this club. But afterwards we will see and you never know.
"Staying in the Premier League is my priority but I am a professional and may have to consider other options when thinking about the future. I'm focused on winning here for the moment. I had different offers in different countries, but the priority for me was coming back to the Premier League and to a club that can challenge for trophies.
"Chelsea is an ideal club because we can still win trophies. If we continue playing in the way we did against Arsenal, everybody will be really pleased. When I say everybody I mean everybody - the fans, the owner, the staff, the players and everybody. When the team is doing well, it will give me a way to move forward."
