#3 Gianluigi Buffon (€52.88 million)
Gianluigi Buffon arrived in the same transfer window as Lilian Thuram, albeit for a heftier fee and as the most expensive Juventus signing for €52.88 million in 2001. Being a goalkeeper, he held the crown as the Bianconneri's most valuable man for 15 years.
Gianluigi Buffon elevated to a legendary status at Turin, staying with the club through thick and thin and also establishing a reputation as one of the best goalkeepers in the world alongside Iker Casillas.
The Italian shot-stopper made 656 appearances for the Old Lady over a span of 17 years. He clinched 11 Serie A titles, 1 Serie B title, 4 Coppa Italia titles and 5 Supercopa Italiana titles with the club. He also made it to Pele's list of 100 best players in the world, the FIFA 100 in 2004.
A beloved figure and a captain at the club, Buffon left Juventus for Paris Saint Germain in the summer of 2018.
