Pieter Collen (born 20 June 1980) is a Belgian former professional footballer who played as a centre-back.
He was part of the Feyenoord squad that won the 2001–02 UEFA Cup, as an unused substitute in the final.
[2] 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.
Feyenoord recalled him but, with Erwin Koeman as coach, he hardly played, partly due to injuries.
On 11 January 2010, he signed for Brisbane Roar in the Australian A-League for the remainder of the season,[3] replacing former captain Craig Moore.
