"We are happy that today's game was easy for us because tomorrow we have big game against the home team. We cannot expect anything but a really a hard game against Poland. They are playing good basketball, but we will try to play better than them. We played against Poland a couple of weeks ago, and we aren't scared at all to play against such a good team."
Orhun Ene, Turkey Assistant Coach:
"We expected more from this game. The next game is important for us because points from this round count in second round."

"If Bulgaria had one player who plays in Eurocup, not even Euroleague, not even NBA, but Eurocup, this team could make a difference. Professional basketball is not to play one or two good games, it's a way of life. You have to give up everything, and that's something that some of our players don't have."
