Nobody can know how good such a young girl could become.
I study astrology and I can tell you something about that.
Ana has got in her natal chart exalted Mars (Mars is God of war). That means she is great fighter and also fearless. She can destroy all her enemies (in this case on sport field). That 's the reason why is she so strong phisically and also mentaly. Second thing is her debilitated Moon which means that she's 'got no mercy' for her enemy (again on sport field of course). Those two things make her a 100% killer.This is absolutely the best combination which one can have to be a 'killer'.
She will never choke. I am absolutely sure about that. That's the reason why she won all 7 final's last year.
Great, so we have a merciless warrior here
What about Donna?
