Polish złoty
Despite efforts from the association of Polonia's supporters to regain control over the club to clear the debts with new sponsors and assure Polonia's survival, Ireneusz Król was not interested. On 28 May 2013, Polonia did not receive a license for the coming season in the ekstraklasa, due to an outstanding debt of around 8 million Polish złoty. Subsequently, the club lost its place in the PZPN (Polish football association) ranks. On 17 June 2013, Ireneusz Król filed for bankruptcy of Polonia Warszawa S.A.
