I lost that favorite to the site that does tactical analysis of the big European games, and also the big international tournies. Anyone know what Im talking about? Something similar to opta. I think it is actually run by one of the big European books
Champions League info can vary pending on the clubs playing, if it is the lesser clubs the only real beneficial info you'd get are from the club pages or UEFA.
In terms of the EPL, as mentioned before you may want to look into the twitter feeds of each club. Sportinglife and Skysports are great for just your run of the mill news.
