The attacker becomes United's fifth signing of the summer, following the arrivals of his former Ajax team-mate and defender Lisandro Martinez, midfielder Casemiro from Real Madrid, full-back Tyrell Malacia from Feyenoord and playmaker Christian Eriksen on a free transfer. United have spent more than £210m in this transfer window to back new boss Ten Hag, while several players such as Pogba, Jesse Lingard, Juan Mata, Nemanja Matic, Edinson Cavani and Andreas Pereira have left.
