Honved's game against Fenerbahce on 30 July is under investigation
Uefa has named five clubs who will be subjected to further investigation into allegations of match fixing.
The clubs are KF Tirana and KS Vllaznia of Albania, FC Dinaburg of Latvia, NK IB Ljubljana of Slovenia, and Budapest Honved of Hungary.
The five were involved in seven games, one Champions League qualifier and six Europa League qualifiers, between 16 July and 6 August 2009.
No matches involving British clubs are under scrutiny.
Uefa is also looking into the roles of three referees and one other official.
The seven games have been whittled down from the 40 that European football's governing body revealed in September it was investigating.
Last week German prosecutors revealed they were looking into match-fixing at around 200 games, which included Uefa's original 40, played in Germany, Belgium, Switzerland, Croatia, Slovenia, Turkey, Hungary, Bosnia-Herzegovina and Austria.
Thirty-two matches in Germany are under suspicion.
Uefa has met with the national football associations of Austria, Belgium, Bosnia and Herzegovina, Croatia, Hungary, Slovenia, Switzerland and Turkey to discuss the matches under investigation.
A detailed Uefa statement said: "Uefa and the national associations will not refrain from taking severe action within their responsibility.
However bitter the truth may be, it must be completely on the table and the sanctions will be tough
Wolfgang Niersbach, general secretary of the German Football Association
"Uefa and the nine associations are fully committed to eradicate these malpractices that are threatening the game. No distinction will be made as to whether this malpractice originates from a player, an official or any other individual.
"Uefa will file criminal complaints, together with the relevant national associations, as soon as possible against clubs, officials and/or players in those countries concerned.
"Uefa and the national associations are facing a case of organised crime which exceeds the investigative power of sports jurisdiction.
"We are grateful to the state authorities for their firm action, also in the interest of sport.
"We will contact the competent authorities in each country to obtain access to the relevant information involving clubs and individuals within their jurisdiction."
Wolfgang Niersbach, the general secretary of the German Football Association, added: "Everyone is interested in a quick and complete solution.
"Despite that we should not allow ourselves to get frantic, but rather we have to give the authorities the necessary time.
"And however bitter the truth may be, it must be completely on the table and the sanctions will be tough."
