Hungarian club Debrecen have confirmed their Champions League match against Liverpool in 2009 was part of a match-fixing inquiry.
Liverpool, who won the game in question 1-0, are not suspected of any wrongdoing.
The Anfield club have told Sky there has been no contact from European enforcement agency Europol or governing body Uefa in relation to alleged match-fixing.
Their home victory over Debrecen came from a Dirk Kuyt goal.
Europol said on Monday that one Champions League match in England was one of 380 games under investigation.
And Debrecen confirmed a report in Danish newspaper Ekstra Bladet that their games were involved.
Debrecen said Uefa had taken action against goalkeeper Vukasin Poleksic in 2010 for not reporting approaches from fixers before two European matches - against Liverpool and Fiorentina.
Poleksic was banned for two years but the Uefa charge at the time only specified Fiorentina.
And Liverpool say they have never been notified by any organisation that the match at Anfield was under investigation.
A statement from Debrecen said: "The (Uefa) disciplinary committee's position was that Vukasin Poleksic neglected his obligations when he didn't report in time that, before two international matches of DVSC, unknown persons attempted to persuade him to influence the outcome of the matches.
"The two matches were the away game against Liverpool and the home encounter with Fiorentina.
"Neither DVSC nor the player wish to react further, all the more so as all the information has been released about this affair during the summer of 2010."
