The Mirror says Villa have enquired about the enigmatic 21-year-old who can play anywhere across the frontline.
Mor has had a chequered career so far in Spain following a £13m move from Borussia Dortmund two years ago.
He has fallen out of favour in the past couple of seasons after he was caught out over his time-keeping. He was banished from the first-team for his indiscretion but he returned towards the season's end as he had surrounded himself with a new team of advisers and was putting his house in order.
Mor was on the radar of every top club in Europe as a teenager and he moved from his native Denmark to Dortmund three years ago.
