When you think of legendary leaders in the game of football, it won't be long before your mind settles on Iker Casillas.The nigh-on immortal Spanish goalkeeper was the man with the arm-band during some truly heady days both for Spain and Real Madrid.He won the World Cup, two European Championships, three Champions Leagues and five La Liga titles - to name but a few of his honours.Casillas was the sort of man that anyone would be happy to follow into battle, leading by example time and time again in pursuit of the biggest trophies in the game.Iker was a colossus in goal as well, regularly making stunning saves in crucial moments and from shots that he had no right to stop.In short, the man was pretty special.However, while his captaincy credentials were clear for all to see on the pitch, it seems he was an adept leader off of it as well.Iker Casillas World CupJOHANNESBURG, SOUTH AFRICA - JULY 11: Iker Casillas, captain of Spain, celebrates victory with the World Cup trophy during the 2010 FIFA World Cup South Africa Final match between Netherlands and Spain at Soccer City Stadium on July 11, 2010 in Johannesburg, South Africa.

Brilliant - at least he was able to take it in good humour.

Having the whole bench laugh at you for a simple slip of the mind is never fun, but at least Casillas and co were able to help him see the funny side of it all.

Coentrao was back among the starters for a Copa final that Real would go on to lose 2-0.
