Football is a team sport with two teams consisting of ten field players and one goalkeeper. Only the goalkeeper is allowed to use hands and the team that scores the most goals wins.

In many ways football is a very simple concept but the simplicity leaves room for much variation which means football is a very physical sport but also full of tactics and technique, leaving room for many different type of players, from heavy defenders through cunning midfield players to fast strikers.

Keynote speakers on football may go for many different angles, focusing perhaps on the sport itself and the history of football, its tournaments, strategies and legendary heroes or delving into questions related to economy and business, including sponsors, advertisement or less pleasant topics such as match-fixing and corruption.
