Treijtel was born in
Rotterdam. He joined
Feyenoord from
Xerxes/DHC in 1968 along with
Willem van Hanegem. On 15 November 1970, Treijtel took down a
gull with the ball from a goal-kick during the derby between
Sparta Rotterdam and
Feyenoord Rotterdam. That gull was later put in Feyenoord's
Home of History, but notable Sparta fans want it to be transferred to Sparta's museum. Treijtel moved to
AZ'67 in 1979. He retired in 1985. == International career ==
