As far as, I'm concerned there are two Fabregasian theories and an equal number of school of thoughts - the suggestions put forth by these different groups from a gooner's perspective is worthy of mention.
The only glaring distinction in their arguments is the salient acknowledgement of the aura his personality tends to radiates on/off the pitch.
Before I attempt to delve a bit into the ideologies of the aforementioned cross section of our enviable fanbase, I think it is pertinent we look beyond the mere assumption (he's just another player, whose time at the Emirates might be up) frequently associated with him.
First and foremost; Fabregas is undoubtedly the most important figure in Arsenal. In case you are wondering, As a player he's equally commited to the short-term cause of the team as well as, the long-term objectives of the club, it shouldn't be hard to work out why Arsene Wenger is so keen on retaining his services, although a vast majority are certain the manager will achieve the feat of binding him to the contractual agreements he signed without duress some moons ago, when he choosed to pitch his tent at the North London outfit.
Secondly; Barcelona are a cabal-operated football scheme governed by a new kingpin, who just like the erstwhile dictator is gearing to flex his financial strength with the help of the ready resources at his disposal, most notably the drafting of Bank loans for incessant player purchases. The supporters of Barcelona and Real Madrid encompass the geographical framework of Spain with regards to unbelievable favours been granted them, to achieve their set goals of global dominance, which in itself isn't bad. Their mission is a laudable one, after all every business-inclined Club has goals and objectives, they aim to achieve in the course of their operation. The only drawback is their corrosive mentality of winning at all costs, transfer-wise Sandro Rosell is only interested in Fabregas' signature for the sole aim of pleasing his natives, who voted on his behalf, during Barcelona's infamous electioneering campaigns.
Finally; Barca want Cesc, while Arsenal are in dire need of the 23-year old, a move to Spain might prove fruitful a harvest for the Gunners, but it's certain to signal the end of his impressive career.
Every gooner is entitled to their opinions, and as such the majority (those who want Cesc to stay) will always be at loggerheads with the minority (those who'd like to be in Wenger's shoes).
The Majority believe Fabregas owes Arsene and gooners alike some sort of quid pro quo given the amazing rapidity of his development from an unfinished Barca youth product to the status of a leader and playmaker in less than a decade.
The minority are in stark opposition to the majority. They want Fabregas to stay also, but will fancy a mega money move which they collectively opine is in the best interest of the club.
Irrespective of your preference, Fabregas is still a Gunner and is certain to be until the next transfer window presents Barca an opportunity to resume their pursuit.
In a lighter mood, Fabregas is currently experiencing the problems he's bound to face if he decides to join his boyhood club. Fabregas' fortunes are dwindling in the midst of his national team-mates, who are being accorded some kind of preferential treatment at the ongoing Fifa 2010 World Cup in South Africa.
Cesc said in a recent interview: "I haven't said that I will definitely leave Arsenal, everything is possible." Translation: I am not yet ready to leave, Pep must guarantee a regular place in his first team is available for me, if and when I decide to join.
Cesc: "Now I have my head and my focus on the World Cup." Translation: I can't afford to be distracted with this boring transfer talk, it could harm my chances of joining the fray from the comfy confines of Del Bosque' Spanish bench.
Cesc: "I am very proud to be captain of Arsenal and I love the club and have respect for them. It gave me so much pride to be made captain." Translation: I allowed my position as skipper to get the better of me, now I know I've made a mistake by publicly indicating my willingness to opt out. As the captain of this great club, I'm ready to make amends and I promise to love the club with all my heart. Oh! Bosque and Barca can go to hell, I revere the Arsenal and their beautiful supporters, and for now I think the English Premiership is the way to go.
