One area of concern for English clubs is the practice of third-party ownership. Under this model, companies or wealthy individuals buy a percentage of a young player in the hope that if his value increases in the future they will make a profit based on their percentage. The advantage for clubs is that they can make big savings from not having to pay the full transfer value of a player and can also make other financial gains, that is, from selling on a player's image rights. Following the problems caused by the sale of Carlos Tevez and Javier Mascherano to West Ham United in 2006, third party ownership was banned in the Premiership, although it is widely used in South America and Europe and is permissible under FFP. Following the introduction of FFP, the Premiership unsuccessfully lobbied UEFA to review the situation to avoid English clubs being disadvantaged, and in October 2011, sports lawyer Jean-Louis Dupont told the BBC that the Premier League's third-party ownership rules were not legitimate and that a legal challenge to overturn them would have a "very, very good chance of succeeding".
