For such a long time in the Olympic men's football tournament it looked like only one team was going to win it, but Brazil had one off-day in the final and the gold medal went to Mexico.
They had gone through the whole competition having things their own way, so when they suffered the early setback of conceding a first-minute goal they did not know how to recover.
Brazil had such a wonderful array of talented young players, but as they set about trying to play their way back into the game several of them tried to do too much on their own. The superior group of individuals was beaten by the better team.
That is something manager Mano Menezes will have to address, but better for such a lesson to be learnt now than at a World Cup or Copa America.
In years to come this generation could go to the very top – especially with a home World Cup to look forward to. For Brazil, London 2012 could be the start of something very special, but they will always look back at the tournament and wonder how on earth they did not win their first ever football gold medal.
Brazil will have a long time for that defeat at Wembley to play on their minds, too. As hosts of the next major tournament they will now embark on two years of nothing but friendly matches.
A lot of Brazil's young players at the Olympics are already full internationals and are destined to become superstars. That they made no secret of their desire to win the tournament helped lift the credibility of football at the Olympics as a whole.
It is difficult for the Olympic organisers to try and find a niche for men's football at the Games, and I think that the format of making it a youth tournament with the concession of three overage players is probably the best compromise. It bridges the gap between an outright youth tournament and a World Cup or continental championship nicely. Seeing future World Cup stars in the making gives it a unique appeal.
I am still not convinced that football - like tennis and basketball - belongs in the Olympics, but at least they have done something different with it.
I never got to take part in an Olympic Games or even in any qualifiers as a player, but those I knew who did I think treated it more as a nice bonus rather than the fulfilment of a childhood ambition. For the athletes and competitors in various other sports, the Olympics is the pinnacle of their ambition. There are so many bigger things in football, that the Olympics can be something of an afterthought.
Interest in the Olympics in Britain was obviously so high that many of the matches sold out, but men's football didn't really provide many big stories in amongst all the world records being broken and heroics elsewhere.
