While displays of arrogance, for the most part, are rightly frowned upon in polite society, there is always a place for it at the elite level of any sport.
Few clubs embody the characteristic quite like Real Madrid. It is a sign of their great conceit that they have just announced the construction of a $1 billion Real Madrid resort in the Middle East, for example.
But Los Merengues have earned the right to look down their noses. After all, they have won the European Cup an incredible nine times, including the first five instalments in the 1950s.
Their current manager, Jose Mourinho, has built his whole psychological approach around imbuing his players with supreme self-belief, and he ha the medals to prove it works.
Their star player, Cristiano Ronaldo, is arrogance personified, but one look at his goal tally and status as the world's most expensive footballer tells you why.
In the latter stages of a competition, an internal crisis in confidence can be more dangerous than any opponent on the field.
In the Real Madrid camp, there is no room for doubt. They believe that this season they are the best, and are just waiting for the chance to show it.
