Van der Hoorn joined
Dundee United in 1989 from Dutch side
FC Den Bosch and stayed at
Tannadice until just after United's
Scottish Cup win in 1994, although he had fallen out of favour by that time. In June 1994, he moved to
Belgium with
Eendracht Aalst and later returned to former club Den Bosch in 1996. After retiring in 2002, van der Hoorn stayed with the club in a coaching capacity, becoming caretaker manager for two short spells in 2005 and in 2009. ==References==
