Бенуа Гру после победы челябинцев над казахстанскими хоккеистами со счетом 5:3 сказал, что он разочарован
The main idea of the text is that the head coach of the Traktor Chelyabinsk hockey team criticized his team's poor performance in the third period of their match against Barys, despite ultimately winning. He believes Traktor became complacent due to their lead in the first two periods, allowing Barys to come back and score two goals. This complacency, he feels, is unacceptable in the KHL as it could lead to bigger problems in the future.
