The undisputed king of this transfer window is agent Mino Raiola. He represents three of Man United’s four signings (Zlatan Ibrahimovic, Henrikh Mkhitaryan, and Paul Pogba), including the largest deal in the history of football. And the name of the Dutch firm raking in his cut of all this action? Maguire Tax & Legal. As in the 1996 Tom Cruise film about a sports agent.
