I have no problem with terry being banned for a red card, but yes, I think the yellow cards need to be reset after the quarters or something because it's silly you can be getting punished for yellow cards back in january and it's depriving match ups of the two best teams in europe. imagine a barca v madrid final without ronaldo and messi, now, I hate them both but it would severly dent the appeal for a lot of people.
the weird thing is, they already have a pretty good rule for the qualifying part of the tournament before the groups. if you recieve 4 yellows you get banned OR 2 in consecutive matches. I don't really have problems with players getting suspended if they have been employed to do nothing more than hack players in both semi final legs, and 4 yellows over 6 matches implies you've been a bit of git over the whole knockout stage and deserve your ban.
