Not long ago, football was not a good example of globalization. The labour market in international club football was highly protected. National leagues like Italys Serie A and Spains La Liga imposed quotas on their teams, allowing them to import only a limited number of players. Some teams could have only two foreign players on the field. This arrangement, however, began to crumble in 1995, when the European court ruled that the difference of treatment of nationals from other EU countries was anticonstitutional. This permitted players to move freely within the EU, and made the club teams much more multi-national. Now it is not unusual for a majority of the players on a successful league team to be foreign nationals.
