I personally think that with both Manchester clubs going out at the group stage, and Chelsea almost joining them will be a good thing for English football, and hopefully in the sake of Chelsea and United a wake up call.
You can't really worry too much if your City, it was your first attempt at the competition, admittedly you blew millions to get knocked out so early, but I'd be very surprised if they don't learn from it, and massively improve next season.
Seeing SAF's face yesterday when they were eliminated made by night, and think it will result in a major overhaul of the United squad come the close season. It sort of happened at Arsenal this season, struggled, sold arguably 2 of their best players and rebuilt. It has taken time, but then again, they were the only English side through before match day 6.
