European football chiefs have asked police to investigate 15 top level games over allegations of match-fixing.

Uefa, the sport's governing body in Europe, said the matches were all played this season, but would not say which competitions were affected and would not name countries or clubs involved for fear of jeopardising the investigation.

No British teams have so far been linked with the inquiry.

A German magazine reported that Uefa was looking into up to 26 matches dating back to July 2005, and said the majority involved teams from eastern and south-eastern Europe.

According to Der Spiegel, the matches under scrutiny include three fixtures from a preliminary round in the Champions League, two in the Uefa Cup and a Euro 2008 qualifier.

But, as officials and coaches from 16 nations gathered in the Swiss city of Lucerne ahead of Sunday's draw for the tournament in Austria and Switzerland, Uefa insisted none of the Euro 2008 qualifying games was under suspicion.

"There are no investigations under way into any of the qualifying matches for Euro 2008," the body said in a statement.

"As a responsible governing body Uefa is continuously monitoring football betting patterns and will take disciplinary action in any cases where that may be justified."
