FIFA's Investigation of West Ham

Most of the newspapers are running with the story that FIFA will investigate the West Ham judgement. However the BBC claim that FIFA is "not re-examining the evidence with the aim of testing the Premier League's ruling."
In effect, as The Independent point out, Sepp Blatter was responding to a question at the end of a press conference. He said FIFA would monitor the situation and also said that,

"According to our files the transfer of Tevez and Mascherano was done correctly according to the international transfer of players."

Furthermore the Premier League is satisfied that there were no irregularities in its judgement,

"We have implemented our rulebook and processes to the letter in this matter and we are more than happy to give Fifa any assurances or explanations they need."
