FIFA has prohibited the ownership of players by third party organisations. The ban is in effect immediately, and was spurred mostly by the massive controversy surrounding the ownership of Carlos Tevez by MSI.

The first incident in this case was the validity of the contract on which he was playing at West Ham, and it began to be investigated late into last season. West Ham United were adjudged to have violated Premier League laws, and were fined a record £5.5 million, but were not docked any points, and Tevez did not serve any suspension.

He was fantastic in the latter half of the season, and almost single-handedly saved the Hammers from relegation. Their safety came at the expense of that of Sheffield United, who were relegated, and responded almost immediately with legal action against the Premier League and West Ham. They called on FIFA and Blatter to intervene, but ultimately their case was dismissed.

The whole situation then intensified towards the end of the summer, with Manchester United's attempts to sign Tevez. Kia Joorabchian, the owner of MSI was claiming ownership of the player, West Ham were too, United were trying to negotiate with both parties, and Sheffield United were watching carefully. Ultimately it emerged that Joorabchian's MSI were the "rightful" owners, but since the league would not allow money to be exchanged between clubs and third parties, a complicated arrangement was finally worked out whereby Tevez signed for United, with MSI and West Ham both receiving compensation, and although there were no official transfer fees, it was indeed a very, very sketchy transfer agreement.

Sheffield United meanwhile re-ignited the fires, albeit in vain, because Joorabchian's part in the whole transfer agreement had proved that Tevez's presence at West Ham the previous season was in breach of Premiership rules.

The whole affair was a huge media circus, and so FIFA have finally acted to try and ban the third party ownership of players. MSI had been a major player in this regard - buying over Brazilian giants Corinthians and signing top players such as Tevez, Javier Mascherano, and Carlos Alberto. Mascherano had in fact joined West Ham along with Tevez, but had been signed by Liverpool in January in an arrangement where a loan/payment arrangement was made with MSI and West Ham. Technically, this was equally as controversial as Manchester United's signing of Tevez, but since Mascherano had been in the reserves, and not playing well, nobody paid much attention or took much objection to this transfer.

MSI had all long intended to make Corinthians into a sort of shop window/clearing house for South America's top talent. Their idea was to buy top players in the region, and negotiate their sales, or partial sales to top European clubs. However, their affairs fell apart in Brazil as well - Corinthians' results were terrible, they lost the fans support, the infrastructure at the club had started to fall apart, and eventual there were also warrants issued for the arrests of Joorabchian and fellow investor Berezutsky by the Brazilian police over financial fraud issues.

On paper, it looks as if FIFA have made a decision to stamp this out, but let's see how strictly they enforce this. Consortiums in Eastern Europe have been running rackets in the trafficking of young African footballers, and in poor countries it will be very difficult to stop this. Additionally, as in the case of Leeds United's purchase of Mark Viduka, clubs can still use third-party investment companies to fund the purchase of players, with the player's registration acting as collateral. It remains to be seen whether this too will be legislated against, or whether it will continue to exist as a loophole.
