I saw a video of her on instagram a few days ago, she said she had some offers from Brazil in the past but was so young and afraid to go. Maybe that is the reason of those rumors.
I read it on a brazilian IG account which shares market news of their leagues everyday (usually worth trusting)...
They also said Minas is giving up on Smarzek because they are probably keeping both Sheilla and Bruna (the first is almost sure, the second one not yet). Well, de la Cruz and Rabadzhieva is far better than McClendon and Acosta.
