And UEFA have confirmed to Perform that punishments could be as severe as disqualification from competitions in progress or exclusion from future events, but that each club would be judged on a case-by-case basis.
The six teams were among an initial list of 31, but the governing body revealed 25 of those cases have now been closed.
According to a statement on the UEFA website: "The introduction of the UEFA Club Licensing and Financial Fair Play Regulations has already had a very positive impact on the scale of overdue payables towards clubs, employees and social/tax authorities, as they have decreased from €57m in June 2011 to €9m in June 2013.
"A similar trend was observed in September 2013."
Malaga and Rapid Bucharest were handed bans from European competition in similar circumstances last season.
