Who are Özil’s best friends? What diet is he following in order to improve his performances? What aspects of his game does he think he must improve on? Some of the player’s best kept secrets were revealed by Mustafa Özil, the Real Madrid star's father and agent.

Mustafa Özil revealed to the German press that his son has a very good relationship with Sergio Ramos and Sami Khedira, and said that the three frequently meet in his son's house, where he often cooks for them. He also said that his teammates' favourite dish was noodles with garlic, tomato and egg.

The player's father revealed that Özil follows a diet which requires him to eat fish twice a week and does not allow him to drink Coca-Cola. He also revealed that his son had gained 4 kg in muscle mass.

Mustafa Özil assessed his son's weak points as well and believes he should improve his goal-scoring record and use his arms better to shield the ball from the opposition.
