Gambrinus Brno coach Jan Bobrovsky praised the second-quarter performance of veteran Taj McWilliams as his team handed out a 75-56 thrashing to Valenciennes on Wednesday.
Brobovsky said it was McWilliams' inspirational scoring, on her way to a game-high 13 points, that paved the way for the Czech side's win over the EuroLeague Women's reigning champions Valenciennes.
They turned a four-point advantage into a 19-point lead at half-time and held that clear margin until the final whistle.
Brno's win moves them into second place in Group A, with a game in hand of leaders Lietuvos Telekomas.
McWilliams, 34, who plays for the Connecticut Sun in the WNBA, led a balanced scoring effort, with Eva Viteckova, Jana Vesela and Alena Kovacova each scoring 11.
"The foundation for our win was the second quarter," said Brobovsky.
"McWilliams was at the top of her game in the second quarter. We controlled the game in the second half and could easily have won by a bigger margin."
"Our defence played well, particularly in the second quarter, and we had a couple of nice fast-breaks for good measure.
Valenciennes coach Laurent Buffard was bitterly disappointed by his side's error-riddled showing.
"I am disappointed by our performance in the second quarter," said Buffard.
"We made too many mistakes and we moved poorly in offense.
"Brno used that to take a big advantage. This was the part of the game which decided our loss."
