"There are number of cases we have been looking at," UEFA general secretary David Taylor (pictured) told a news conference after the UEFA Congress.
"It's very complex and very difficult to find proof. But within the next couple of days we will be issuing charges against one club."
Taylor did not disclose what country the club was from. In September UEFA said it was reviewing 10 matches from the current UEFA Cup season and 15 from last season for irregular betting patterns, all in the competition's preliminary rounds.
UEFA will launch a gambling investigating unit next season featuring experts who will review suspected irregularities in matches from European competitions.
"UEFA is setting up this betting fraud detection system across Europe to include 27,000 matches in the first and second division in each national association," Taylor said. "Only a few matches cause us problems but we are determined to root out this problem."
UEFA president Michel Platini called match fixing "a serious risk to football."
"Through this early warning system we will find out what bets are being placed," Platini said. "I'll be extremely firm with those who cheat. I don't accept players who cheat and will suspend them from any activity in football."
