At the same time the signings of Mascherano and Tevez were being investigated by the Premier League, who were concerned that details regarding the transfers had been omitted from official records and whether the influence of MSI, led by Kia Joorabchian, breached Premier League rules regarding third party ownership of players. The media touted the idea that Tevez's contract could be terminated, possibly resulting in a deduction of points for playing an ineligible player. On 27 April 2007, West Ham pleaded guilty and were handed a record £5.5 million fine by the Premier League, but avoided a points deduction. Liverpool's signing of Mascherano was investigated and he was cleared to play after a two-week delay.
