Jose Mourinho is represented by super-agent Jorge Mendes (right)
Mourinho is represented by Mendes, who helped broker his move to replace Louis van Gaal as Manchester United manager in May.
United have mainly dealt with fellow high-profile agent Mino Raiola this summer, going through him to sign Paul Pogba, Zlatan Ibrahimovic and Henkrikh Mkhitaryan.
But while United have splashed out around £150m on those three stars and defender Eric Bailly, Mourinho still wants more signings.
According to the Daily Mail, Mendes is due in Manchester today for talks with City over the future of defender Eliaquim Mangala.
Squad players like Matteo Darmian, Marcos Rojo and Phil Jones are facing uncertain long-term futures, while Chris Smalling has yet to start under Mourinho.
