The second game is a worse result for Arsenal . It ' s ONLY a worse result because of a contrived rule . They were both ties and neither game was technically worse than the other without that . At home Arsenal played better offense than PSG did at home . At home Arsenal played worse defense than PSG did at home . At home PSG played worse offense than Arsenal did at home . At home PSG played better defense than Arsenal did at home . Outside of a contrived rule , neither did better . Period . Rules won ' t change anyhow , so keep complaing as long as you want about them if that helps you to live with them . Really , what we were discussing is the rule and whether it ' s good or not . Not whether PSG won the group fairly , obviously they did . You haven ' t made a single point except to act as if a higher scoring tie on the road is somehow better than a lower scoring tie at home . Literally you can ' t articulate why , but you spout it . The reason you can ' t is because it ' s clearly no better or worse .
