Villa is a favourite of Tottenham boss Juande Ramos and is also being tracked by Chelsea owner Roman Abramovich.
He said: "My future is the same as always. We'll see what happens in the summer. I want to succeed, to score goals for Valencia and Spain ... I need to enjoy my football. We'll see what happens.
"I will consider my situation in the summer. We will look at where we are and what the club intends to do. But until then I will dedicate my work to Valencia."
