While the 22-year-old could stay if Villa remain in the Premier League, agent Eris Kismet admits if a big club like Inter were to make an offer, they would evaluate it.
He told interlive.it: "I have had no contacts with Inter personally and I don't know if the two clubs have spoken about him. Certainly Inter is one of those clubs where Christian dreams of playing.
"A move in the summer? In football everything is possible if the three parties find a solution that makes everyone happy.
"But if a big club like Inter were to make an offer, we'll evaluate it."
