Well said and true.
People seem to relate, or respond well to certain aspects of players games, and thus the players. For example (and I was typing this before I even read down to where you named these players) you could tell just by your attitude that you appreciate the O'Shea, Fletcher and Rooney types.
My favourite current players at Arsenal are Clichy and Sagna. Mainly because Clichy gives 110% each game, and you can see him putting in the 1%er efforts, the last ditch tackles and the gut running. As for Sagna well he gets on with his game with little fanfare, does his job week in week out and works his socks off for the side.
And it's fair to say some supports just love the club that little bit more than others, though I think this may come with years of support and going through both the good times and the bad. The newer generation of fans - ie the influx of fans that were lured to the club thanks to the likes of Ronaldo - are, and have been, spoilt for success. They can't relate to the struggling club, the constantly upset supporters and nor would most of them have the stomach for it. After years of supporting the club you'd like to think things would change there, but it's down to the individual.
