I believe his most recent comments where he states he's not 'desperate' to leave tell us everything we need to know about him potentially throwing his toys out of the pram. If he stays, he'll put his head down. Throwing a tantrum and fecking everyone off would indeed be counter productive for everyone, himself in particular. Add on the fact it's a world cup year and that the whole saga will have very much been a thing of the past when his ban is over, and we'll see a return to normal quite quickly in my opinion.
As for fan reaction, it's a certainty that he'll be gee'd on as soon as he gets on the pitch and performs a nutmeg or two. The current level of outrage & condemnation towards Suarez from the Liverpool fan base is expected, but doing my head in a bit at the moment. It's a reality that loyalty is very rare in football. Personally, I can understand his motivation when asking for a move - it's just the joining Arsenal bit that makes it a sensitive situation.
I think the whole thing goes beyond Suarez' value on the pitch, too. Fact is, we're a shadow of the club we used to be but it's imperative that we hang onto our elite aura for as long as possible. Selling our best player to the 4th (not 1st, but 4th) best club in the land would set a new, dangerous precedent.
