It will be business as usual for Paul Pogba when Manchester United face Celta Vigo this evening despite a Fifa investigation into his £89million from Juventus.

The world governing body are looking into claims that agent Mino Raiola is set to pocket £41m from the world record deal and are conducting a probe with their Transfer Matching System (TMS), the online platform that monitors cross-border transfers.

Asked if the stories had affected him or Pogba, United manager Jose Mourinho said: "No. The question is simple. He asks the facts and, no, he isn't affected."

Neither the player nor Raiola has commented on the latest developments, while a spokesman for United said on Tuesday: "We don't comment on contracts."

The claims will be explained in greater detail in a forthcoming book called 'Football Leaks: The Dirty Business of Football', written by two journalists from German newspaper Der Spiegel.

The book will allege that Italian-born, Dutch-based agent Raiola will receive payments for acting for the buying and selling club, as well as the player.

Acting for all three parties in a transfer is unusual but allowed under certain circumstances, and all details must be logged with FIFA TMS.

Mourinho was speaking ahead of United's Europa League semi-final second leg against Celta Vigo at Old Trafford on Thursday - the first leg finished in a 1-0 win courtesy of a goal from Marcus Rashford.

The Portuguese told the pre-match press conference: "For Celta it is, in their words, the most important match of their history. And my feelings, it's also the most important match of our history.

"It doesn't matter what happened before, it doesn't matter how big matches we played before. 'What matters is the next one."
