When Barcelona smashed the world record transfer fee to sign Diego Maradona from Boca Juniors for £3 million in 1982, the football world was stunned.
The Argentine may have been the world's finest player but the fee paid out seemed hard to believe. Just two years later, Maradona was breaking the record again, this time moving to Napoli for £5m. Where would the madness end?
Fast forward to 2017, and Paris Saint-Germain would not be getting much change out of £200m to sign another South American player in the Brazilian attacker Neymar.
From Maradona to Neymar, via Zinedine Zidane and Cristiano Ronaldo, the record had been beaten 20 times on some of the greatest talent ever seen on the football pitch.
Take a glide through the photo gallery above, as we take a look those star names and see at how it worked out for both player and club.
