Aimar is keen for a move to England to join former boss Rafael Benitez at Liverpool.
Argentine international Aimar, 25, is not a regular in the Valencia side under Claudio Ranieri, the former Chelsea manager.
The midfielder told the Daily Star: “This season I’m not happy at Valencia.
“Rafa Benitez is an excellent coach who knows me very well and Liverpool would be an ideal place to go if I cannot sort out my future here.”
“I do not understand why I have not been playing. Ranieri has not told me the reasons but I am obviously not part of his plans.
“From what I can see, English football is the best in Europe next to Spain and I do not think I would have a problem adapting to the Premiership.”
