Sleep/work is a huge factor. Earliest games are on at 1245am, lastest games are on at 845am (mostly mid week games, I have work at 830am) I watch replays on the Sunday, or just watch live text commentary at work. As said above, I'm not gonna get up at 4am to watch Chelsea vs Leicester or a Champions league group game, but will if its Chelsea vs City etc, or an important cup tie
