Germany under-21 manager Horst Hrubesch once said, "We in Germany are prone to rave about foreign players. We praise Wayne Rooney to the heavens, likewise Ronaldo or Messi. But we have our own Messi. Our Messi is Özil." In the UEFA Euro 2012 qualifier against Belgium he scored a goal which has been described as a "work of art." Germany coach Joachim Löw hails Özil for his 'genius moments' and his performance without the ball.
Real Madrid midfielder Xabi Alonso described Özil as "the kind of player you don't find these days," adding, "He understands the game, sees things, combines and thrives between the lines, unlocking teams," while José Mourinho said, "Ozil is unique. There is no copy of him – not even a bad copy." Mourinho also stated that, "He is the best number 10 in the world. Everyone loves him and sees a bit of Luis Figo and Zinedine Zidane in him. He will make history at Real Madrid."
Assistant coach of the Germany national football team Hans-Dieter Flick says, "We are proud to have him in our team. When he has the ball, you can feel the excitement and astonishment among the fans." Former Holland international Ruud Gullit labelled German Özil as a "technically perfect" player who has "total control of the ball" and has "great imagination".
Enough said.
