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
