Let's start with what we all know to be true: It's time to give up. ...scratch that: It's time to make history. Never has a US or Canadian club finished a two-game CONCACAF series in Mexico and emerged victorious (although Montreal came desperately close in 2009). The remaining MLS clubs in the current Champions League will have to buck the trend to reach the semifinals. On the positive side, if any of them survive, there will be every reason to think that they can win it all, since finishing a knockout tie in Mexico is pretty much as bad as it gets in the CCL.
