Although it will be incredibly difficult to ever match his contributions on the pitch, it's vitally important for a former club legend, like Henry, to publicly address his concerns regarding the direction of this club... regardless of those who still feel that Henry has some sort of agenda due to the backlash he received following earlier comments he made on air regarding Arsenal, he has an intimate understanding of the game, he knows the fans are being hosed and he feels some sense of obligation, both professionally and personally, to tell it like he sees it... much like I've continually expressed
over the last couple months, this team isn't evolving under this current ownership / management team... instead we are currently experiencing a «stagnant» phase in our club's storied history... a fact that can't be hidden by simply
changing the formation or bringing in one or two individuals... this team needs fundamental
change in the way it conducts business both on and off the pitch or it will continue to slowly devolve into a second tier club... regardless of the euphoria surrounding our escape act on Friday evening, as it stands, this club is more likely to be fighting for a Europa League spot for the foreseeable future than a top 4 finish... we can't hope for the failures of others to secure our place in the top 4, we need to be the manufacturers of our own success by doing whatever is necessary to evolve as an organization... if Wenger, Gazidis and Kroenke can't take the necessary steps following the debacle they manufactured last season, their removal is imperative for our future success... unfortunately, I strongly believe that either they don't know how to proceed in the present economic
climate or they are unwilling to do whatever it takes to turn this ship around... just look at the current state of our squad, none of our world class players are under contract beyond this season, we have a ridiculous wage bill considering the results, we can't sell our deadwood because we've mismanaged our personnel decisions and contractual obligations, we haven't properly cultivated our younger talent and we might have become one of the worst clubs ever when it comes to way we handle our transfer business, which under Dein was one of our greatest assets... it's
time to get things right!!!
