Do we need him, was the original question.

Which now becomes the new question, what sort of team are we without him? The answer is obvious. If Wenger has completely lost the plot, rather than being in an accelerating process of losing it - if he's hit rock bottom, then he'll let both Ozil and Alexis leave next month. The shop window reasoning you are now applying as the latest argument doesn't seem to be going so well for Alexis. We all know what a great player he is when he's on form. Right now his head is not in the game. He's the most likely to leave next month. There seems no hope of retaining him and Wenger and the leech squad will want at least some cash. The fact they passed up 50 mill in the summer shows how incompetent they are so you never know, but perhaps even they can make a rational call given a second chance. So if Ozil is staying until the summer he still has plenty of time to set up his shop window. The fact is, he's doing the business now. He was doing it before, but because he couldn't pull this team up single-handedly he's been scapegoated. He's come through all that nonsense, shrugged it off and continues to be a vital component that provides much needed quality to a team sorely lacking in other areas. It will be a massive hit to lose him that could only be compensated by a genuinely world class replacement signing. And that's where the new backroom team come in. If they get the authority to act we might be okay. If they are hobbled by the incompetent and selfish git who has diligently created this shitshow then we are in real trouble.
