Pieter Collen

On 11 January 2010, he signed for Brisbane Roar in the Australian A-League for the remainder of the season, replacing former captain Craig Moore. It was announced on 6 May that he had not been offered a new contract for the next season despite earlier indications that he would be retained by the club.

To maintain his physical fitness he trained with NEC in the first half of the 2008–09 season. In the second half, he provided his services to amateur outfit SC Cambuur. After failing to earn a longer contract with the club he continued his career in the Exqi League.

The turning point came halfway through the 2003–04 season when he was loaned out to NAC Breda again, where he played 51 matches in one-and-a-half seasons. Feyenoord recalled him but, with Erwin Koeman as coach, he hardly played, partly due to injuries. When February arrived he started to play regularly again and was man of the match on several occasions. In the 2007–08 season he fell out of first-team contention and only appeared for the Feyenoord reserves. In the January transfer window, he returned to his homeland, signing with Sint-Truiden until 2010. However, his contract was annulled at the end of the next season.

Once he arrived in Rotterdam Collen started on the bench. Due to good play in training, he forced himself into the squad and played many good matches in the Dutch top flight as well as in the UEFA Champions League. However, a string of injuries and a long period of rehabilitation caused him to be sidelined until the end of the 2002 season. He was part of the Feyenoord squad that won the 2001–02 UEFA Cup, as an unused substitute in the final. When he was declared suitable to play again he was loaned out to NAC Breda but suffered another a season-long injury and returned to Feyenoord.
