AC Vantaan Allianssi (or AC Allianssi) was a Finnish football club, based in the town of Vantaa. Allianssi have been a club in decline since an 8-0 defeat at fellow Finnish club FC Haka. The match was believed to have been fixed by a Belgian-Chinese betting cartel, which took control of the club in summer 2005. A subsequent police investigation failed to find sufficient evidence of match fixing though.
