He is the second AC Milan player on this list. Costacurta and Paolo Maldini played together for a number of years before he eventually retired in 2007.
Costacurta played 663 matches for AC Milan. However, the center-back scored just three goals in his entire career with the club; one in the 1989/90 season, another in the 1991/92 season, and the last one in his final season; the 2006/07 season.
The record-setting goal came on the 19th of May 2007 in a 2-3 loss against Udinese Calcio. Costacurta was 41 years and 25 days old when he scored the penalty against Udinese. This match in which he scored his third and final goal would coincidentally also be his final game of the season- a season in which he played only 11 games of.
With this goal, Costacurta became the oldest player to score in Serie A in the 21st century, and also the oldest player to score for AC Milan.
