Manchester United's summer transfer window of 2022 could well become a case study in years to come of the difficulties of assessing value in the modern game.
After splashing out a record £225million on six new players, the perception within football is that the club overpaid for the players they signed.
Landing Christian Eriksen on a free transfer and Tyrell Malacia for just £13million plus add-ons was impressive business, but they had to cough up a potential £56million for Lisandro Martinez, well above their opening offer for the Argentine.
