Quintero claims he would prefer a move to Inter Milan after being linked with United.
The Pescara youngster spoke to Gazzetta dello Sport as he bids to win the South American Under-20 Championship with Colombia.
When asked if there will be a plane booked to Manchester afterwards, he replied: "No, I like Inter. It is clear that I would not say 'no' to other good teams but I think big: Manchester, Milan, Juventus. I will decide with my family and agent. I like Inter better because they have many South Americans. And I'm fine in Italy."
