The difference between having an Ozil and not having Ozil is the difference between Messi playing for Argentina/Ronaldo playing for Portugal and Messi playing for a Barcelona/Ronaldo playing for a Real Madrid.
I'm not confused, sometimes things need saying more than once so as to affirm that their importance cannot be overstated
And it seems bizarre not to think that you wouldn't have the best creative midfielders to complement the top strikers. And considering there aren't many creative midfielders out there who have Ozils footballing ability, range of passing and vision it seems obvious that that is harder to replace than a goal scoring winger/striker (yes it will cost us but there are more players of that kind avaliable)
In that sense Ozil becomes more irreplaceable because he is a rare breed, maybe I am confused because I don't know how to explain that to you in any simpler way. You don't have to agree, I have already made it abundantly clear that I'd have to go a long way to find something I care less about than what you think.
But it seems bizarre that I seem to be talking a foreign language to you, I have an opinion which you vehermently disagree with, I'm not even asking you to respect that view because see above but as you seem to be inferring stupidity on my part I am choosing to come to the conclusion that you must have the capacity to understand what I'm saying, but maybe that's an assumption too much.
