Got three of them in this particular order.
(1) For just plain old up to the almost exact second scores use
http://futbol24.com/
(2) For not quite as fast at the above site, but a better analysis use
www.xscores.com
(3) Finally, the most detailed and sometimes faster than xscores, and where standings are available for most leagues use
www.activescores.com
Hmmm, I normally use the bwin or interwetten live score feature. I prefer interwetten in that matter as they have a sound feature, letting you know when a goal is scored and where.
