Online Sport Manager Games

I used to play both hattrick and managerzone but found those 2 games quite sluggish since hattrick was 1 game a week and managerzone was 2 games a week and it feels like seasons can last forever with those games, so I didn't play them both for very long. Both these games were good but its a shame there isnt another one of this style but plays its games daily so seasons don't last months. Top Eleven is daily matches but you find that your team always progresses, not like a relegation/promotion pyramid system that managerzone/hattrick has.
