Paul Pogba's Manchester United transfer being investigated by Fifa

Fifa has opened an investigation into the transfer of Paul Pogba from Juventus to Manchester United, Fifa have confirmed.

The £89million paid by Jose Mourinho’s side was a world record fee, with the France international smashing the previous benchmark set by Cristiano Ronaldo’s move away from Old Trafford to Real Madrid.

But after leaked documents showed how much super-agent Mino Raiola earned from the deal, football’s governing body has now opened an investigation into the deal.

It’s claimed that Raiola earned a staggering £41million from the transfer, which is the focus of the investigation.

The fee was said, by Football Leaks in their new book, to have been split into three separate payments.

Raiola was reportedly paid a percentage of the transfer fee, which totalled roughly £22.8m, future payments to be paid in instalments (16.39m) and an extra payment to his agency based in Monaco (2.2m),

Fifa confirmed they are seeking clarification over who was involved in the process and how much they were paid.

Pogba arrived in a summer of heavy spending for the Red Devils, with Henrikh Mkhitaryan and Eric Bailly both arriving, while they also brought in Swedish great Zlatan Ibrahimovic on a free transfer.
