Benitez's camp met with Samp last week.
"Sampdoria was very serious, very professional and they have a project," the Spaniard told Sky Sports News.
"My idea is to find a club that can match my desire, my expectations to challenge for trophies.
"This time Sampdoria was really good, I was really pleased as they were thinking of me but I am waiting for maybe another option.
"The priority is England but I have to be ready for any other challenge.
"I try to find someone that will be at the top and take on the challenge for trophies, the Premier League, Champions League, and Europa League so something that you can win."
