The Octopus?

There is suppose to be this amazing octopus that predicts the winner of the world cup games, but could it be that this octopus is actually really the cause of the winner? I think this octopus thing could all be explained by psychology. The players the octopus picks would become confident, and the other team then thinks "oh no... it is going to be so hard to win this time." and does worse. So... no offense octopus :)
