Everton have been investigated over the transfer of Ibrahima Bakayoko.
Quote from Daily Express
The Ivory Coast forward was sold by Everton to Marseille on July 10 for £4m in a single payment, despite a fax from agent Dennis Roach to Jacques Santini at Lyon, saying Everton were ready to accept no less than £3.5m, or £3.2m in a single payment.
Everton payed Mike Morris of World Football in Monaco £450,000 on August 5th 1999. Apparently by Everton giving Mike Morris and World Football £450,000 (12.85 per cent of the fee), they got out of the operation only what it was, in reality, expecting. Robert-Louis Dreyfus confessed to finding the fee paid to Everton dear."
