I agree. But football is, unfortunately, mostly played without the ball. Özil was poor when we didn't have the ball in the first half.
Also, I mentioned before that I don't think Özil was good enough offensively either in that first half. If you watch the clip above, then you will see that in the first half he didn't make a single run into the box where he received the ball, and overall he hardly got out of a jog. Playing at 10, I expect him to properly support the striker! He MUST make runs beyond the striker, he MUST get himself into the opposition box and in goal scoring positions. He did all that brilliantly in the second half, but he was far too relaxed and comfortable in the first half for my liking.
Defensively, using the clip above again, it is easy to notice that Özil didn't really have any defensive actions at all in the first half. He did nothing of note. In the second half, where Watford was a lot less in our half, he still managed to have several occasions where he worked hard defending deep in our half, and there were several occasions where he actively tried to pressurize opponents.
You all know I love Özil. He is easily my favorite player in the world. I still think he was utterly disappointing in the first half yesterday, and I expect better.
