We can not stay where we are at present, either physically or psychically; but looking far ahead we may descry an ultimate state in which, organically associated with one another (more closely than the cells of a single brain) we shall form m our entirety a single system, ultra-complex and, in consequence, ultra-centrated....

What all these have in common is that, without any central control, individual units (genes, cells neurons or workers) respond to simple, local information, in ways that allow the whole system (cells, brains, organisms or colonies) to function: the appropriate number of units performs each activity at the appropriate time.

Are some of you on here missing a few brain cells as fans There is nothing Arsenal or Wenger can do with the Sanchez situation He wants to leave and has been offered 400k a week in wages who in their right mind is going to turn that down as a player As for blaming wenger who has been our most successful manager helped us build a stadium gave us 20 years of cl football and some of the best teams the ol has seen Including the invincible and you all have the Gaul to trash the man as if he has done nothing for the club I suggest you should look at the plastic fans in the Arsenal blogs that have created a toxic atmosphere at the club They attack their own players in a daily basis why would any top player come to s club where the manager the owners and players are shamelessly attached constantly Yet Wenger wins trophies regularly even them that is derided Look at Spurs Liverpool they win fuk all every year yet their fans back then Look at yourselves and all the negativity that you have created striking the club before you blame Wenger for everything I have been a season ticket holder since the 70s and never have I seen our fanbase been so full of entitled morons who have stopped backing the club and constantly deride the club snd attack it We have the worst fanbase in football you have made this great club a lagging stock in world football All you now us fans constantly moaning If you don't like Arsenal fc then buy out kronke and run the club or fuk off and support someone else You won't be missed Coyg

The point I was making is that Arsenal is owned and run by billionaires that would sooner take money out than put money in and while you might not need a cash injection at this moment in time, anyone with half a brain cell will know that your club has had financial leg - ups in the past so to accuse City of being somehow different to what's gone on in your history is both hypocritical and incorrect.
