Nyon, Switzerland - European football's governing body UEFA said Friday it would be seeking "the harshest of sanctions" for players or clubs involved in the latest match-fixing revelations. UEFA said it was cooperating closely with German police and prosecuting authorities who are leading the investigation which covers some 200 games in nine European leagues.
The federation said the three Champions League and 12 Europa League matches under investigation were all early qualifying round games.
The games are part of the UEFA list of 40 matches that have previously been quoted as being under suspicion. More information will be given on which matches are concerned at a later date, UEFA said.
"UEFA has been actively involved in the investigation and has given assistance via detailed information through its Betting Fraud Detection System," a statement said.
"This detection system monitors all UEFA competitions and European national league first and second-division matches for suspicious betting patterns. The information on a number of matches was passed to the German authorities upon their request."
UEFA said the case proved it was possible for a state investigative authority to work closely together with a sports governing body in investigating corruption or match-fixing.
"We will continue our battle against any form of corruption in European football with a mission of zero tolerance," UEFA said.
"UEFA will be demanding the harshest of sanctions before the competent courts for any individuals, clubs or officials who are implicated in this malpractice, be it under state or sports jurisdiction."
