I found this article. It's in Greek but I translated it for you guys
The article follows the title of this thread actually. As many of you know, Maria's mother was a great player who reached #43 in the WTA rankings, was a Greek Fed Cup player for years and reached the Olympic QFs as well as the third round of Roland Garros twice.
Maria said here that she is determined to sacrifice a lot for her tennis, such as holidays, times with friends, etc. (good to see that she has her priorities straight!). Maria said that she learned about her mother's tennis career when she was 11 years old. She went to her grandmother's house and saw her mother's trophy and played with it even though she didn't know what it was. Her mother didn't want her children to play professional tennis because she knew how hard it was. Maria then talked about how she is very proud of her mother and her achievements in her career.
Maria's mother was then interviewed and talked about how her family means everything to her. She said that when Maria told her she wanted to be a professional tennis player, she panicked because she knew how hard it was. She said she knows how hard it is for Maria because she also went through that. She said that everyone asks her if Maria is better than she was, but she said its very different because back then they played with wooden rackets, and she was better on clay but Maria is strong and fast (so she plays better on fast surfaces). She admits that back in her playing days sometimes she would skip practices, but Maria is very different because she always practices, wakes up early, runs, and watches her diet. She believes in Maria and thinks that she will be in the top 100 in 3 years. She said that her father (Maria's grandfather) was the first to recognize her talent (he is/was a tennis coach). She also said that the times have changed and now the Greek federation has no money so Maria's family has to cover all of her expenses, but they believe in her.
