Rosemeyer remaining cautious about a Final repeat for Germany
The forward is one of several players competing in Bourges who experienced the highs of a truly incredible run to the Final of the competition last summer in Udine.
It was a special experience and one that will never be forgotten. But the tricky situation at this edition of the event is whether to harness those memories for motivation or bury them - to avoid any complacency.
That conundrum became more intense as Germany completed their eye-catching 79-54 success against Netherlands - at the same time as Spain demolished Lithuania. It was something which immediately threw up the topic of a potential Final repeat.
"Last year was the first time I had played at the FIBA U16 Women's European Championship and so to get the silver medal was an amazing experience for me," mused Rosemeyer.
"Of course we have to think about similar goals because this time and we also have an opportunity to go to the FIBA U17 Women's Basketball World Cup.
"But, this is living in a totally different world this time around. Memories are memories and I do speak about them sometimes with Emily [Bessoir] for example - but now it's all new. We have to start all over again."
She continued: "I think we played well against Netherlands with it being the first game and with everyone being a little nervous - we did a good job.
"I think it is normal to feel this way at the start of any tournament and even if it was against Netherlands which is a derby, it had to be just another game to us.
"Our mind is focused on only winning."
Rosemeyer was perhaps always destined to shine for her country, since playing the sport was a no-brainer in her home.
"Basketball is in my blood because my whole family plays," she smiled.
"My older sister [Leonie] is also playing for the national team and we all absolutely love it.
"Basketball is a perfect sport and it is something special in my life that I will never change - I just love it so much," concluded Rosemeyer.
