Still, Paris Saint-Germain's signing of Gianluigi Donnarumma for a big fat zero in transfer fees sounds like a sensational piece of business – particularly after his Euro 2020 heroics.
The Italy goalkeeper has left Milan, his boyhood club, to join Mauricio Pochettino's side where he hopes to be able to challenge for the biggest club trophies, most obviously the Champions League.
Certainly, Donnarumma is right to aspire to the top prizes. This is a player who made 200 appearances for the Rossoneri by the age of just 21 years and 146 days, who was valued at €170million by agent Mino Raiola when he was just 16.
PSG have secured a bargain, for sure – but is it one they really needed?
As Opta data shows, Navas, a four-time Champions League winner, may well have a point.
