Real Madrid recently agreed to pay £80 million for one man - Cristiano Ronaldo. Not only is this a huge amount of money in real terms, it's a huge amount when compared to other football transfers. It eclipsed the previous world record, which was set only days earlier, by more than 40%.

So why did Real Madrid spend so much? Firstly, they had been performing relatively poorly and were seeking to improve their performance. In doing so, they bought into the 'hero fallacy'. This is a tendency we all share to place a disproportionate emphasis on individuals when explaining success. Essentially, we explain the outcomes of amazing events by paying attention to the most obvious causes - the leader or outstanding performer. The fallacy is that the real causes are often too subtle and less visible to us, so we overemphasise the part played by the most visible - the heroes.

The second reason Real Madrid spent so much is they failed to take into account 'regression to the mean'. This is the principle that the more extreme a performance (either very good, or very bad) the more likely it is to move back toward the average. Why? Ronaldo's outstanding performances were based on three factors - his ability, his form, and luck. Whilst his ability is a constant, his form and luck will vary over time. The £80 million price tag reflects Ronaldo's performances when he was in good form and having the rub of the green. As his form and luck inevitably changes so his performances will decline, even though he still retains tremendous ability.

So what does this tell us about managing a business in a downturn? Like Real Madrid, many businesses will be desperately keen to improve their performance. With this there comes the risk of overreliance on following or recruiting 'heroes' - the highly visible individuals who will single-handedly turn things around. Instead, organisations should remember that success is rarely predicated on one person alone and that everyone, even the best, will waver at times. In many ways the answers can be found in the world of football - the best teams tend to have two features - good players throughout the team and good teamwork. The conclusion, therefore, is to focus on getting and retaining good people across the business, and to ensure good communication, with everyone working towards the same objective.

And what lies in store for Ronaldo? No doubt he'll score some spectacular goals, but without 10 colleagues backing him up, few of them will be winning goals.
