If Argentina had equalized the score and won the World Cup on penalties, it would have been the most unfairly won World Cup in history. They didn't have a single shot on target for 90 minutes, so they don't deserve the title at all. Congratulations to Spain, who did it in style. They really should have won this match by at least 3-0!
If it should happen like you mention, It doesn't make it an unfair victory, sometime luck goes way beyond expertise, the team with the highest possession, shots on target can still lose the game against their opponents that had few touches and advantages.
Of course, something like this can happen, and I've seen matches like this before. I mean, it would be pretty unfair to have something like this in the World Cup final.
Spain deserved the win, if Argentina was lucky to equalize, that is just some football magic, we've seen it happen against England, I don't think it is anything new if it happened again, Argentina losing the final equaled how they performed in the final, and it's well deserved.
Well, I don't think so. In this match, in the first 90 minutes, Argentina didn't even have a single shot on goal, so it's not magic anymore, it's a disaster! I would prefer this team not to win the World Cup. Certainly not in a match in which he doesn't even have a single shot!
