lorentino Perez quite often appears to not to 'get' things, it would seem that he has trouble understanding others and showing empathy toward Real Madrid players. According to El Confidencial, well connected to Real Madrid, the club president is upset at the reaction of players to the departure of Mesut Ozil. The same newspaper looked like it had been used to do the groundwork for the transfer, Ozil was accused of acting up to get a huge pay rise and even fabricating interest from other clubs in order to pressure Perez.
It didn't work, much as it looked like Real Madrid were trying to turn people against Ozil, there was still a huge reaction to his exit. The situation has put Perez and new signing Gareth Bale under pressure. If the move doesn't work out then the discontent at losing Ozil and paying twice as much for Bale is only going to grow, and Perez doesn't like it. Arsenal are still in a state of delirium and it's no problem for Wenger, but it must be nice for fans of the London club to know how much Madrid misses Ozil.
El Confidencial insist that Real Madrid players knew all about the tactics being used by Ozil to try and get a big pay rise and therefore say that Perez has been shocked by the reaction of the dressing room. The plan from the boardroom at Real Madrid clearly didn't work and now they just want everyone to keep quiet and get on with things.
The better Ozil does at Arsenal then the worse it will be for Perez to insist he did the right thing, unless Bale is an instant success.
