The former club chief criticised the way that the Portuguese acted while in charge at Santiago Bernabeu and praised his successor, Carlo Ancelotti, for his own methods
Mourinho guided los Blancos to three Champions League semi-finals and won one La Liga title, one Copa del Rey and one Supercopa de Espana during his three-year spell at Santiago Bernabeu before departing by mutual consent for Chelsea last summer.
The Portuguese was constantly at odds with the Spanish press and was rumoured to have irked a number of first-team players in his final campaign at the club, with his benching of Iker Casillas in favour of Diego Lopez a particular sore point among supporters.
Madrid snapped up ex-AC Milan coach Carlo Ancelotti from Paris Saint-Germain to replace him and, with a treble still potentially up for grabs this season, Calderon believes that getting rid of Mourinho was the right choice.
"Jose Mourinho, in my opinion, wasn't the right man for a club like Real," the 62-year-old, who reigned at Real Madrid between 2006 and 2009, told BBC Sport.
"At Real, we have some codes of behaviour. A lot of people didn't like the way he behaved.
"Carlo Ancelotti brought something different and that is perfect. The behaviour of the coach is the first image of the club."
