Wonder how long it will take until Özil can actually have a great game without people arguing that he's still not a good fit for Real Madrid or why Isco is better anyway. Who cares, anyway? Özil has not suffered from leaving Real Madrid at all, on the contrary. He's had two great performances for Arsenal without having had any time to settle in and has immediately shown his value and class. So what does it matter to him if Isco is a better fit for Real Madrid? That doesn't diminish his ace performance.
Also, a lot of people seem to forget how young Özil is. He moved to Real Madrid at only 21 years old and directly became a starter, even though a lot of people prophesied he wouldn't make it because he was too young - that says enough about him dealing with pressure, actually. And talking about pressure, the largest amount of pressure was put on him during the world cup in 2010, when Ballack got injured and everybody doomed him and called him too weak and too young to perform. How did he deal with it? He showed some world-class performances against teams like Argentina and England and lead Germany to the semi-finals.
He's 24 years old now and still hasn't reached his full potential. Real Madrid is probably not the best place for a player type like him to fully develop and bloom; Arsenal is a better destination in that regard. He still has a couple of years ahead of him before reaching his peak to further improve, and at Arsenal, he's at an ideal place to do so. And he will. I actually believe he will become a better scorer there, too.
That doesn't mean Isco is not a great player, but I prefer to wait and see how he develops before saying he's better a better player than XY, or vice versa.
On a second note, great performance from Özil yesterday. Man of the match for me.
