Away goals are kind of pointless these days. They were introduced at a time when it was difficult and time consuming to travel abroad and teams had a genuine physical disadvantage playing away from home. These days, when players travel first class, take their own chefs, and stay in 5 star hotels, is there really any difference between playing in London, Paris or Madrid?
But... some part of me will be a little bit sad. Yes away goals are illogical and yes it ruined some games. But there were times when the away goals rule introduced a fascinating knife edge into games. That situation of chasing a goal, but knowing that conceding would essentially mean game over, made for some fascinating tactical situations. And as a fan, that feeling of scoring an away goal - a sort of double goal - was incredibly sweet.
