When can a 51 year old Portuguese man state a simple fact and call into question your entire raison d'etere?
When your entire career can be summed up as: "failure is not winning a title in seven or eight years."
When you are paid 8 million pounds a year (over six hundred and fifty thousand a month) to create a team that you have full authority over, including transfers, and your ideas for improving the team are to spend the entire transfer budget in one go, £42 million, on what is already the strongest point of the team; the midfield; questions will be asked.
When the painful truth is so obvious it's better to avoid reality. Failure at Arsenal is captured inside of a shell of pretty football, such a pretty, shiny, shell. The team's success is so often rubbed to a glistening pointlessness like an old trophy that can no longer be claimed. Temporarily remembered perhaps, most usually by the way of 60 passes that result in nothing but "Ooohs" from a holder-ship that pays top prices to see top prices and can only steal points plucked from those more affluent in their spending.
When the mind is no longer capable of driving the formula 1 car but the ego demands it, and the body cannot accept it; there is a point where there is only one possible outcome. The glorious unfortunate fireball is there for all to see. Arsene, like many greats, must come to terms with the end of his period in the sun.
Whilst he can still cross the finish line one last time. Strength, tenacity, the ability to just make sense generally is gone. It happens to many if not all. The inner strength to admit defeat is there, but the substance of the man will not allow it. In a club that would rather sell it's greatest treasures rather than realise them he is the perfect, blinkered, manager.
The joys we can take in victory against one and other are temporary pleasures, sometimes we get to leave behind a nice mess. Wenger would say: "But wasn't it pretty." And he would be right. He created a beautiful thing and one must remember the unfortunate fact: Defeat in the end is for all of us.
