FIFA have launched an investigation after Sampdoria filed a complaint over the transfer that saw Bruno Fernandes sign for Manchester United from Sporting Lisbon.

United signed Fernandes for £47million in January and the Portuguese playmaker has enjoyed a stunning start to his Old Trafford career. 

But Serie A side Sampdoria have claimed they are due a slice of that fee, having negotiated a 10% sell-on clause when selling Fernandes to Sporting in June 2017 for €8.5 million.
