Dawid already has a baby and wife in process of divorcing. I bet daddy Robert doesn't like it at all.
Who knows, maybe Aga has had the credit card out and is helping financially. She is, fundamentally, a good person and it wouldn't surprise me. Her sister will have a word in her ear if she gets carried away I am sure. The coach has a watchful eye as well. Regardless, I doubt she will be easily taken advantage of, especially after seeing her press conferences during the last Fed Cup vs Israel. I have never seen anyone want to be somewhere less than the coach at that short press conference when Aga put her foot down and decided they would turn up but they would not answer questions.
