An EU court ruling says FIFA's transfer rules are too restrictive. This ruling increases player power and threatens the viability of some soccer business models.

A decision could force soccer’s governing body to rewrite the regulations that govern the sport’s multibillion-dollar transfer market.

Some of FIFA's rules on player transfers go against European Union laws and free movement principles, the EU's top court said on Friday, in a ruling that could open the door for players to find a new club more easily after their contract is terminated.
