( CNN ) -- When it comes to the theater , Jose Mourinho is the man who really does seem to sense that all the world 's a stage . On his return to the Bernabeu following the winter break , Mourinho was cast as villain once again as the home crowd poured forth their ire onto the Portuguese coach . Forget that Real won this game against Real Sociedad 4-3 and did so after playing with ten men for most of the contest . ' I hate my social life , ' says Mourinho . It was Mourinho 's decision to leave goalkeeper Iker Casillas , a national and Real treasure on the substitute bench , which had irked those in the stands . The natives are unhappy with Mourinho 's management style , not to mention the fact that Real sits 16 points off league leader and great rival Barcelona after just 18 games . Casillas , who started on the bench , entered the action after just six minutes when fellow goalkeeper Adan was sent off for a professional foul . The Spain international played the remaining 84 minutes , but Mourinho was still subjected to criticism from the stands . `` Perfect . Let them whistle me before the match and then support the team as they are doing . I think the whistles are for leaving Casillas out and also because we are not achieving our aims in the championship , '' Mourinho told reporters . `` There are others who did n't applaud and are not happy with his ( Casillas ' ) performances . If I am not doing well it is normal that they whistle and it is something you have to live with . I do n't want to be a hero independently of my performances . '' `` I told Adan before the game that the whistles he is likely to hear are for me and not for him but in my opinion there was a lack of respect for him . `` He is a player who has been 16 years at Real Madrid , he was born in Madrid and he did n't deserve that . `` Adan deserves to be happy but I do n't know why in Spain that happened . The problem is that the press have turned an attack on Jose Mourinho into a lack of respect for Adan . '' Cristiano Ronaldo and Daniel Craig - A right to privacy ? While supporters may have been angry at Mourinho , they were at least treated to a thrilling affair with Real Sociedad playing a full part . Xabi Prieto scored a hat-trick for the visitor , but still could n't prevent Real from taking all three points . Two goals from Cristiano Ronaldo and further strikes from Karim Benzema and Sami Khedira sealed the win . Sociedad also finished the game with ten men after Dani Estrada was shown a second yellow card in the 80th minute . Vilanova returns . Elsewhere , Barcelona welcomed coach Tito Vilanova back from cancer surgery with a comfortable 4-0 win over city rival Espanyol . Vilanova underwent an operation to remove a tumor from his lung after suffering a recurrence of a problem on his parotid gland -- located at the back of his mouth . Is Barca boss Vilanova coach of the year ? `` I would like to thank everyone for their support , '' Vilanova told reporters . `` This club has had a lot of knocks in the last couple of years but I always want to take the positive approach . What has happened to me could have happened to anyone . `` This is not over yet and there will be days that I can take training and others I ca n't , but I want the media to realize that this illness is mine and it is private .
