Ramis, 27, is now keen to continue his career in England after snubbing a switch to Everton two years ago.
And Villa and the Black Cats would not have to break the bank. Ramis, who has three years left on his contract, earns a modest £11,000-a-week in wages with the La Liga outfit.
He admitted: "This could be the ideal moment to make a change, and the Premier League appeals. I want more challenges, more dreams."
