Speaking at a Manchester United Foundation event to launch a Red Devils' Legends match against Real Madrid on June 2, Butragueno, now a Real director, offered no obvious reason for optimism about United's chances of getting the 2008 world player of the year back.
"Cristiano is under contract and we are very happy with him," he said.
"We are delighted he is at Madrid because he is a fantastic professional, and very ambitious in a positive way.
"His contribution to the team and the club has been amazing since he arrived.
"We are very grateful he came to us and are lucky he plays for Real Madrid."
