Yeah but it will be hard for Modena to overtake Chemik on points ratio if they lose the match 1-3. But it is possible I guess
Not sure about the answer to your question. If Modena or Chemik win the group they will go through. If conegliano win the group (this will happen if they beat Telekom 3-0 and Chemik beat Modena 3-1 I think) then one of Chemik and Modena will still go through as a 3rd best 2nd place team unless Azerrail can get a point vs fener and beat Dabrowa I think.
Ah this all makes my head hurt
