I don't have a team, Milan are the closest to what I call almost being a fan.

I don't even have a favorite player anymore, at least none that currently plays. The 5 I liked retired, and the club I was a fan of stopped being that club after Kaka, Maldini and Carlo left. And Brazil is another thing, but they too have more than a few thugs in disguise as players. Still, I watch Brazil NT matches anytime I can.
You can say that I've evolved.

Outgrown the sports a bit maybe, yes. Your case is different, I've seen the highs of the past, and the present does not compare. So it's uninteresting to me. Even if we do win the CL next somehow, it still will not match the 2007 triumph for me, which will not match the loss at 2005, which will further not match the win in 2003 (that one was sweet). And so on.
Point being, I like the sports for what it stands. Little more than that now.

I do like watching quite a few names, and always like seeing quality stuff on display, some tough neck-to-neck affairs, fair play, champion sportsmanship. That for me is the beauty of the game, and what sports stand (or stood for) in general. And I struggle to get that out of my head.
Granted you don't see that quite often now, what with the falling standards, but hey, I'm not complaining. Much. This new football is a dirty, dirty affair. And almost as worse is the falling standards in all departments. Give me one goalkeeper that can touch the heights of a Buffon or Oliver Khan.

None come close.
Same goes for most strikers and midfielder. Can you see how much of a dearth (oh, I love using this word) we have now of really visionary playmakers. It used to be a glut a few years back. What we have now are either mechanical and military (like Emanusleon, or the type that Allegri likes), or the real creative ones are lazy basturds.
And so I do care, when I see teams like Leverkusen being clueless during a match. It's a small nail in the coffin for me when it comes to footballing standards. And it hurts like a small nail too.

I mean, if we, with a weak, weak team hold Barcelona to 0-0 and go there without our first choice midfield, attack and more importantly defense, and hold them to 1 goal (those two penalties don't count for me), then Leverkusen should be doing better.
Long rant, I know, but that's that. It's the falling standards of the game that irks me the most. And I blame commercialism and the glut of money for it. Pretty soon the spirit of the sports will die (if it hasn't already), and I am not sure I'll be watching it as much then. Just like cricket after the advent of the money making events like IPL and Twenty20.
