Stefano Seedorf started his playing career with amateur side Hellas Sport, but like his cousins he would soon be discovered by Ajax.
After rising through the ranks with players such as Serginho Greene (Feyenoord) and Youssouf Hersi (Vitesse Arnhem) he made is debut in the first team line-up on 30 April 2002, just 2 days after his 20th birthday. However, after 2 years and just 5 league matches Stefano was sent away on a loan spell with NAC Breda.
In NAC Breda Stefano made an immediate impact. He proliferated himself as a fast paced technical midfielder and scored 7 goals in 29 matches. Despite his successful performance with NAC, his contract with Ajax was not extended. In the summer of 2004 Seedorf was therefore transferred to FC Groningen.
