FIFA are to wade in to the row between the Premier League clubs, the league and West Ham over the registration of Carlos Tevez.
The world governing body president Sepp Blatter has stated that he is ‘monitoring the situation very carefully’ and will intervene should it prove that the league has been too lenient.
West Ham were fined £5.5m for irregularities over the signing of Carlos Tevez and Javier Mascherano but they escaped a points deduction.
However FIFA has said that it is not re-examining the evidence with the aim of testing the Premier League's ruling.
Sheffield United, who went down on the final day of the season, are leading the fight against an independent commission's decision not to punish the Hammers with a points deduction.
A Premier League statement read: ‘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.’
