Sixteen clubs enter the competition at this stage, the other eight main round slots having been filled following August's preliminary round. Iberia, maintaining their unique record of featuring in every edition, are in Hungary for Group 2 against hosts ETO FC Győr and preliminary qualifiers KMF Tango Sarajevo and FC Grand Pro Varna. Also starting on Tuesday is Group 4 in Cyprus, where AC Omonia Nicosia welcome regular threats FK EP Chrudim and FC Litija plus Baku United FC, the first English side to make it this far.
On Wednesday, former semi-finalists Marca Futsal are in a tough Group 3 alongside hosts FC Lokomotiv Kharkiv, who supply the Ukraine squad that qualified for UEFA Futsal EURO 2014 last week, Sporting Club de Paris and Tulpar Karagandy – gaining a debut entry as Kazakhstani champions Kairat Almaty won the European crown in April. The other past semi-finalists in action, Araz Naxçivan, also begin that day in Group 6 in Romania while the last of the six sections kicks off on Thursday in Riga, among the contenders the first German team to reach this round, Hamburg Panthers.
