Yes. This is my next random blog post about soccer. I know what you're thinking. What's taken so long, right? Well, I'll tell you. You see, the thing with random blog posts is you can't rush them. They just happen when they happen. It's part of their charm and appeal. So here you go.
The away goals rule is a way of breaking ties in playoffs where opposing teams play against each other twice, once on each team's home field. The rule stipulates that if the aggregate score is tied after completing both games, the team that scored more away goals wins and the other team is eliminated. If the number of away goals is a tie, then an additional 30 minutes of extra time are added to the second game, followed by penalty kicks if necessary. This approach is used in many important soccer competitions worldwide, including the UEFA Champions League, the UEFA Europa League, and certain qualifying matches for the UEFA Euro Cup and FIFA World Cup. There are also many other competitions that use the rule.
Now that you know what the rule is, let me get to the point. It's a dumb rule. It is redundant and unnecessary. The problem of home-field advantage has already been solved by playing a game at each team's home field. Adding the away goals rule results in a competition that values home defense and road offense above road defense and home offense, which is not very meaningful. Sure, if everyone agrees to it, then great, but I would hate to be the team that loses by that rule.
The most prominent example I can think of is the Champions League semi-final between Chelsea and Barcelona in 2009. The first game, played at Barcelona's stadium, ended in a 0-0 draw, which meant that Chelsea failed to score any away goals. The second game, played at Chelsea's stadium, ended in a 1-1 draw. The aggregate score was 1-1, but since Barcelona scored their goal on the road, they moved on and Chelsea was eliminated.
Based on the final scores of the two matches, Barcelona had the stronger offense on the road since they scored an away goal and Chelsea did not, but Chelsea had the stronger defense on the road since they didn't allow any goals at Barcelona's stadium while Barcelona allowed one goal at Chelsea's stadium. So the away goals rule, as stated previously, values a strong road offense above a strong road defense. It seems arbitrary. Isn't it just as impressive to stop the home team from scoring as it is to score goals on the road?
In conclusion, the away goals rule is meaningless and arbitrary. It doesn't send the better team through to the next stage. It's just a way to decide who "won" because that's a decision that has to be made.
Some might argue that there isn't really a better way to do it, so let's analyze the alternatives. I don't like penalty kicks, but I think I would prefer them over away goals. At least that way you can hang your hat on something that feels a little more real, if only a little. Extra time can be a good option, but it gives an advantage to the team that plays at home during the second leg. This could be acceptable if the advantage is given to the higher seeded team. They may already use seeding in this manner, but I'm not sure. The only other suggestion I can think of is to play a third game at a neutral site, but I don't really like adding more games.
Based on the above analysis, my final proposal is to give the higher seeded team the home field for the second leg and to eliminate the away goals rule completely. Extra time and penalties can be added as usual at the end of the second leg if necessary.
