Manchester United's current squad is the most expensive in football history, according to research from the CIES Football Observatory. The world-record acquisition of Paul Pogba from Juventus took the Reds' spending to more than £600m ($771.4m), and into unprecedented territory.
United appointed Premier League-winning boss Jose Mourinho during the summer and his arrival sparked a spending frenzy, with United agreeing deals for Eric Bailly, Zlatan Ibrahimovic and Henrikh Mkhitaryan, as well as the purchase of Pogba from Juventus.
