Mourinho is expected to return to Chelsea at the end of the season.
AVB said: "When he left (England) he wasn't that well loved by a few of you guys (the media) and that was something we talked about.
"He was loved in all the clubs where he has won titles, in Real Madrid the same.
"There is maximum respect for what he has achieved, but for it to be at the level of Real Madrid's expectancy, we will never know. Probably not, but he certainly has won a league against a dream Barcelona team, which is a great achievement."
