I love watching Özil on a football pitch, so I am probably a bit biased here, but I think we are a far better team when he is on the pitch. That goes for his apparently 'piss poor' spell last season as well. We are more fluid, we retain possession better, we create more chances, and Özil is, for me, at the heart of all that.
He has sublime technique, everything looks so effortless, and he just glides across the pitch, always on the move. Özil creates space where there is none, and he has that very, very rare ability of looking like he always has time on the ball even in a league as fast paced as the PL.
I have always preferred thinking players like Özil over action players. That's why, for me, Ronaldo isn't even in the same stratosphere as Messi as a footballer, and that is why I much prefer watching Özil over Alexis. That last part drives my 14 year old nuts; he just can't comprehend how anyone can prefer watching Özil over Alexis, and I can't properly explain or show him with game sequences (God knows I have tried).
