Although Serie A is not the world's best league, it is most definitely the world's most competitive league. Of all of the elite football divisions Serie A arguably has the most teams with a chance of winning the league. In England and Spain it is often the same teams competing with one another each year, but in Italy any of around 6 teams are usually in contention to win the title. Also, top teams in Italy can go from being a powerhouse in to a struggling side within a short while. No league boasts this amount of unpredictability and this makes the Italian Serie A the most unmissable league in world football. With teams like Inter Milan, AC Milan and Juventus, the tough part will be deciding which jersey to wear.
