SLUC Nancy Head Coach Jean-Luc Monschau:
"First of all congratulations to Oostende for this victory. Unfortunately we cannot continue our streak of winning games. Today we were out-rebounded by a team that was more hungry to win this despite our fabulous comeback in the 4th quarter."
SLUC Nancy player Kenny Grant:
"We were outrebounded in this game. I have the feeling that we were not ready for this game. They really killed us on the boards. If we want to win on the road we need to show a different mentality."

"What a win. I am very happy for the team, for the fans, for this club and for myself. After all this these close games we've lost the last weeks it feels extremely good to win this one.

BC Telenet Oostende player Marcus Faison:
"We deserved this win. This team has enough talent to win more games than we did so far. We just need keep our heads up, definitely in the last quarter. Unbelievable how we let them come back in the game."
