He played for a number of Danish clubs, most notably Boldklubben 1893 (B 93) in the Danish Superliga, as well as a number of foreign clubs (Sweden: Kiruna FF, England: Torquay United, Finland: Finnpa, China: Guangzhou Apollo, Norway: Saskatchewan Gjøvik-Lyn). Haddaoui started his career playing for Danish 1st Division side Avarta, where he attracted the attention of Danish Superliga clubs Football Club Copenhagen and Lyngby Football Club. He had a few training sessions with Scottish First Division side Airdrie in December 1995, but could not agree personally on terms, and he eventually rejoined Avarta in the 1st Division. In March 1996, Haddaoui joined English 3rd Division club Torquay United on loan.
He made two appearances as a substitute in his month at the club, before moving to Finnish club FinnPa for the rest of the season.
After a successful season in Finland, where Haddaoui finished as the league"s second highest goalscorer, he moved to Chinese Jia-A League side Guangzhou Apollo on a 10-month contract in February 1997. He returned to Denmark in August 1997, following reports of cultural shock and poor living from Haddaoui and Danish teammate Kim Rasmussen.
Haddaoui joined Hvidovre IF in the Danish 1st Division and after making 10 goals, he joined the Norwegian Club Gjøvik Lyn. His single goal was not enough, as B 93 were relegated following their single season in the Superliga.
Haddaoui joined Copenhagen rivals HIK in the 1st Division in 1999 and played for 2 and half seasons, making an impressive 48 goals.
He was still playing part-time for HIK in the Danish 2nd Division in the 2001-2002 season, while working as a web consultant for webmagazine Ingeniøren.
