Neymar's near-£200m transfer to PSG from Barcelona in 2017 turned the football world on its head and ushered in the future of absurd fees we see today.
Don't get me wrong, transfer sums had been on the rise but the Brazilian's move sparked an incredible initial chain-reaction before setting a new standard for what a player is worth.
The summer of 2022 saw another example of this, with a mad scramble for defensive midfielders hiking prices to such a degree that players purchased for seven-figure sums a couple of years prior could be on the market for over £100m.

The Red Devils forked out £70m for the then-30-year-old, who at times in his debut campaign looked like the club's most important player. Still, even in during that run it was hard to make a case for the eye-watering figure.
