5 Most Expensive Signings ever made by AC Milan

Inter Milan v Barcelona - UEFA Champions League — The Rossoneri have been big spenders in Italy with some of the biggest stars playing at the famous San Siro.

#1 Rui Costa

Manuel Rui Costa of AC Milan celebrates as his team score — Rui Costa was signed by Milan after helping Fiorentina to three Serie A titles during his time with the Viola.

Rui Costa became the most expensive signing for AC Milan when he signed from Fiorentina at the start of the 2001 season. Fatih Terim brought the player to the Rossoneri when he joined the club, paying a mammoth €44 million for the Portuguese who didn't disappoint - helping Milan win the Champions League in 2002/03.

Costa also went on to win a Serie A title, a Coppa Italia, a Supercoppa Italiana and one UEFA Super Cup with the Italian giants, before Kaka replaced him as a starter in the team - as the Brazilian became the world's best player under Carlo Ancelotti.
