UEFA says five clubs in Albania, Latvia, Slovenia and Hungary are suspected in European football's biggest match-fixing investigation.
The game's European governing body says the the clubs are KF Tirana, FC Dinaburg, KS Vilaznia, NK IB Llubljana and Honved.
They're said to have fixed seven qualifying round games in the Champions and Europa Leagues between July 16 and August 6.
UEFA's general secretary says match-fixing is a "cancer we need to eradicate".
Gianni Infantino says the even matches are among 40 in continental club competitions previously identified as being under suspicion.
Infantino says UEFA is also investigating three referees and one official connected to UEFA but no member of UEFA's administrative staff is suspected.
