The Real Madrid head coach responds to those who were critical of him selecting Antonio Adan ahead of the club captain in their 3-2 defeat to Malaga
Many eyebrows were raised before the game had even begun when it had been revealed that the Portuguese coach was choosing to favour the inexperienced back-up shot-stopper.
But the ex-Chelsea and Inter boss insisted that Adan is performing better than Casillas at the moment, in his opinion, and insisted that there was no other motive than form in his selection.
"It was a technical decision, the coach’s decision," Mourinho told reporters after the match. "It is the coach who analyses the situation and the players that are available, and then the coach chooses his team to play.
"It is a purely technical decision. You can invent the stories you want, but it is a technical decision, nothing more. My opinion counts and no others.
"In my opinion, Adan is better than Iker at the moment. As it's the coach who chooses, and as I have only as valid opinions of my assistants, we have decided so."
Despite suggestions and rumours that Mourinho is unhappy at the Santiago Bernabeu, but the coach stated: "I'm not considering quitting and I’m not worried about my job."
Mourinho believes that the fortnight off will be invaluable for his players, who he has accepted are unhappy with results and tired from a busy first half to the 2012-13 season.
"This [winter break] comes at an ideal moment. The players are sad and empty of energy," he added. "If we think of the point it is no motivation, but if we think of what Real Madrid means, then we have motivation.
"Losing always hurts, but especially when you don’t give 100 per cent, but today we gave everything we had. As I said to the players afterwards: they can go with the sadness of losing, but they have the right to relax because they gave all they had tonight."
