FIFA has announced it is investigating Paul Pogba's £89million transfer from Juventus to Manchester United last summer.
A FIFA spokesperson told Press Association Sport that the world governing body was looking at the deal through its Transfer Matching System (TMS), the online platform that monitors cross-border transfers.
"We can confirm that FIFA TMS has been requesting information on this matter. We have no further comment at this stage," said the FIFA spokesperson.
This is understood to be linked to claims that agent Mino Raiola will earn £41million from the world-record deal that saw the French player return to Old Trafford.
