|Full name||AC Vantaan Allianssi|
Allianssi were a club in decline, following 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. In 2006, a former managing director, Olivier Suray, admitted that the notorious match was fixed. However, he accused Chinese owner Ye Zheyun for fixing.
On April 11, 2006, club chairman Erkki Salo announced that the club would be filing for bankruptcy with immediate effect.
