I agree, but continuing across 2 legs is not without issues. We were able to play at home (that it was not our usual home is nobody's fault but our own) while Tigres will presumably get a "home game" at some bubble location with limited to no fans. And if we score 2 goals or more at this neutral location, we get an Away goal advantage that isn't really fair to Tigres. It would make sense, I think,at a minimum, to suspend the AGR for these resumed legs. If the match is tied after 180 minutes, regardless of Away goals, go to extra time or kicks and ignore Away goals.
But there is a much bigger problem with the Club America- Atlanta matchup. CA won the first game 3-0 at Aztec Stadium, one of the toughest Away settings in the world. I don't think it is fair to force Atlanta to play Game 2 at a neutral site while having to live with the result of an actual away game at Aztec Stadium. As it turns out, Atlanta is crap and it probably doesn't matter, but it would be quite unfair to make them try to overcome a 3-0 away loss at some sterile campus like the Orlando Sports Complex. I'm not sure how the CCL committee will handle this. I could see them voiding the games. OTOH, I doubt they have the brass to take a win like that away from CA.
