Hargreaves joined United from Bayern Munich for £18million, but has struggled with injuries at Old Trafford.
“For Owen’s sake it is important we say he is not for sale,” said Ferguson.
“Selling the boy is not even under consideration. It is a good story. The fact he has been injured a few times since he has been at the club.
“But United people remember what a contribution he made to us winning the European Cup. He was available in the second half of the season and played some important games for us.”
