The new-look team that added Spanish internationals Amaya Valdemoro and Anna Montañana, and Czech national team players Jana Vesela and Ivana Vecerova to their already star-studded squad, achieved its first aim on Thursday by winning the Supercopa Femenina in Valencia.
New coach Isma Cantao looked on with joy as his Ros Casares outfit prevailed 72-50.
"It's important to start with a title, and when you play at home in front of your fans," said Ros Casares captain Elisa Aguilar, who hasn't had much of a break after playing for Spain at the Olympics in China.
"I think that this year we are more balanced in the team. We have brought in good Spanish players, and the pressure is always on us as we have to win at Ros Casares. I think getting to the EuroLeague Women Final Four is something that we have to do."
Laia Palau, another Spain international of Ros Casares, scored six points but made contributions in every aspect of the contest and was voted MVP of the Supercopa.
"I am surprised but very happy with being voted MVP," she said.
Brazilian Erika De Souza led Ros Casares with 14 points.
