It was plainly obvious why he was signed - the German fit Arsene Wenger's philosophy the same way Steven Gerrard symbolised Liverpool, it was a perfect match.
The Gunners' attractive style of play is embodied within Ozil's game. Therefore, when he arrived for £42 million, many felt it was the deal of the summer.

Up until recently, however, Ozil has failed to replicate the scintillating form he displayed for Real, for whom he dazzled with ferocious consistency and an eye for presenting his team-mates with unlimited chances on goal.
The provider soon became the outsider at the Emirates; it was obvious he needed time to adapt. The Germany international lacked the physicality required to play in the Premier League, with many claiming he was a luxury player - aesthetically pleasing, but lacking in substance.
There were glimpses of his prowess, of course, but he never quite did enough to justify himself as a world-class player - until now.
Against Everton last weekend, he gave one his finest performances in an Arsenal shirt. Composed on the ball, graceful and clinically accurate when passing, Ozil took the game by the scruff of its neck and dominated from start to finish.
His beautifully weighted cross which set up Olivier Giroud was the touch of finesse needed to break the deadlock - only Ozil could have plucked out such a ball.
The way in which he waltzes around defenders is a sight to behold, unlocking space for those around him to attack with pace. His vision, awareness and diligent creativity set him apart from all else.
When Arsenal and Ozil are playing at their peak, they are capable of beating anyone, encapsulated by their 2-0 win over Bayern Munich last week.
This was a game many expected them to lose, yet the north Londoners were remarkable. Solid in defence; deadly in attack, a sheer determination resonated throughout their performance, with Ozil producing another exemplary display.
He kept everything ticking throughout the game. His decision-making in attack provided Arsenal with a foundation to build from, whilst defending tirelessly with the rest of the team - something the Ozil of old wouldn't have done.
The German has finally arrived in north London, and whilst many will argue it's come two years too late, if his form and creative influence is able to steer Arsenal to a Premier League title this season, his fee will be seen as money well spent.
