Antonio Adan has suffered because of Jose Mourinho's poor man-management of Iker Casillas, Graham Hunter told Revista.
The Portuguese coach once again opted to go with the inexperienced 25-year-old stopper and leave his World Cup and multiple La Liga and Champions League winning keeper - and club captain - Casillas on the bench for the home game with Real Sociedad on Sunday.
However, that move back-fired when Adan was sent off after just six minutes for bringing down Carlos Vela in the box. Mourinho was forced to bring on Casillas and, although Madrid went on to win the game 4-3, Hunter believes the former Chelsea and Inter Milan's policy is not beneficial to the club.
"I've no doubt this is a disciplinary thing based on a running feud," said the Spanish football journalist. "It's the wrong decision, for the wrong reasons, at the wrong time.
"I have sympathy for Adan; he's a decent guy, with whom Casillas has a terrific relationship, a guy who could have gone on to be Real Madrid's goalkeeper, potentially, or gone on to another big club. He was persuaded to stay in the summer but this is part of the premium for having stayed.
"[This situation] is not helping Casillas, nor the club, nor Adan - and that makes it the wrong decision."
Hunter also believes Mourinho's personality is clashing with the attitudes of his players and says the coach - despite his success elsewhere around Europe - is struggling to manage the big names at Real.
"This is the first time Mourinho has gone to a club that he can generally say is the biggest club the world, the first time he has been to a club where the players are routine winners of every single trophy you can imagine," said Hunter.
"I don't think he knows where the stop button is, when to leave them in peace and when not to torment them.
"His ego has come into it and that is his key fault."
Hunter also aired his views on:
Mourinho being booed when his name was announced before kick-off
"At the last league game before the break they decided not to announce his name for the first time in his career at Real Madrid. They didn't want the whistles and boos to have a negative effect on the team - it's the first time he's experienced it in his career. This time they re-instated it - a coach should be able to have his name announced at his own stadium - and the response was negative. What worries you is he's not listening to that barometer of public opinion, he doesn't care."
Concern in the boardroom about Mourinho and the direction of the team
"There are elections at the end of the season (the candidates must declare themselves by March) and Real have got a run of games that could include cup Clasicos, league Clasicos and will include the Manchester United game. [Real Madrid President) Florentino Perez must be watching this and not only be worrying about the league performance of the club but his own future, too."
