Dmitriy Bazelevskiy, BC Khimik head coach:
"I agree with every word that the captain of the team said. The beginning was really tough. We lost a lot of balls in the first half of the game. I think our attack was fine but we couldn't lead it to the result. We were so nervous that we couldn't get together. I hope that every player will draw a conclusion for himself. There is nothing impossible. The opposite team was much stronger, with a wonderful players, with a great experience in the EuroChallenge. Though we managed to show a fight."
Don Beck, Eiffel Towers head coach:
"A wonderful game. Physically hard one. The only thing I was surprised of was the huge difference in three-throws. I would like to wish good luck to the coach of "Khimik" in Ukrainian Championship. We liked your arena and the city."
Jerome Beasley, Eiffel Towers player:
"We got ready for a very difficult physical game. This team fought for every ball. Though the score during the game was huge but "Khimik" didn't give up and fought and that was difficult for us. We couldn't believe that it was happening. But we've got ourselves together and in the last seconds won the game."
Andriy Agafonov, BC "Khimik" player:
"We didn't manage to accomplish anything from what we planned. At the beginning of the game we were walking on the court. I can't explain why. Maybe because we got scared. It's seemed that we looked forward to win the game. The beginning was terrible. Our game was not confident. After the main break we started play our defense and managed to bring the score level. But the luck was on the side of the opposite team. Unfortunately, Sasha Kolchenko missed one of the free throws. I could make a rebound but failed."
