Player FMP Zeleznik, Filip Covic:
"We played a good game and psychologically this was very an important victory for the team. In the first quarter we played weaker but our team is young and this is the reason why at some point we went down. In future games, we will certainly give our best to win."
Coach FMP Zeleznik, Sloodan Klipa:
"We didn't play well in Amsterdam, we hoped that during this game we will show our true quality. We showed that we can play good basketball and we didn't repeat the mistakes from the previous games. The players were nervous at the start of the game but at the end we grabbed victory."
Coach MyGuide Amsterdam, Arie Shivek:
"From the start we played like we discussed in the locker room, however we went through a period (5-6 minutes) in which we couldn't find a solution for some specific players. FMP has a very young and talented team, I believe that in the future some players will be part of strong European teams. Congratulations to FMP, the better team won tonight."
