If you were looking for a really interesting match between two football giants, then probably you would have to wait for the right time or season, for the most famous and excellent football tournaments are held seasonally anyway.
Back on track, the three most famous football tournaments in the world would undeniably be:
• the Olympics,
• the World Cup, and
• the UEFA Cup tournaments
Football was first introduced into the Olympics in the year 1900, with the first set of medals given out some eight years later; during which professional footballers from clubs were not allowed to represent their countries initially.
As for the World Cup, which returns every 2 years on common occasions, this was introduced by FIFA in the year 1930. It started with merely 13 countries in the beginning and thus far has expanded its territories up to Japan and Korea in recent years.
The UEFA Cup on the other hand returns to fame every 4 years and involves football giants from all over Europe. This tournament does not have a fixed amount of countries or teams, however, and the number notably changes every year to date.
