Nyon, Switzerland: UEFA is investigating six Europa League clubs for failing to pay debts on time.
UEFA says they are: Skonto (Latvia), Slask Wroclaw (Poland), Vitoria Guimaraes (Portugal), Pandurii Targu Jiu (Romania), Petrolul Ploiesti (Romania) and Metalurg Donetsk (Ukraine).
The clubs will be investigated by its Club Financial Control Body, chaired by former Belgium prime minister Jean-Luc Dehaene.
UEFA says sanctions are expected next month. They could include fines, withholding prize money and suspensions from the Champions League or Europa League.
The six clubs were among the 31 identified by UEFA in September as being monitored for overdue payments of wages, transfer fees or taxes.
UEFA says the other 25 cases are closed.
Clubs must settle "overdue payables" to obtain a license from their national association to play in UEFA competitions.
