The Brazilian centre-back's current contract with the defending German champions runs until the summer of 2014.
"I don't think about [my future] right now," he told Ruhr Nachrichten. "I talked to my agent but I will only decide after this season. I have read a lot about interest from Schalke, Hamburg, Hertha Berlin or Hannover. But it is a fact that nobody has contacted me yet.
"There are no official offers. Of course, Spain and Italy are interesting countries. But to be perfectly honest, for sporting reasons mainly, the Premier League is of interest.
"The Bundesliga is the second best league in the world. I play there now and that is pretty good. I am nearly 27 now, 30 is not far away. I want to play in Europe a bit longer before I return to Brazil to play my final match and enjoy life at the beach."
Santana joined Dortmund from Figueirense in 2008.
