In an interview to Ekstra Bladet, Caroline Wozniacki's coach and father Piotr spoke about how rheumatoid arthritis influenced the Dane this year. As translated by Mark Nixon, Piotr said: "Everyone who has her illness knows what she's accomplishing.
We others can't understand it. I'm proud of her, both as her father and as her coach, because I know a lot of things we haven't told the rest of the world. Caroline has never wanted to use her illness as an excuse for anything.
She's just tried to do the best she could. It was impressing seeing how much time she still spent keeping herself going and getting ready for new matches." Piotr complained about the lack of consistency: "The problem is, we can't have practice sessions at a high level for any length of time because problems with different things always arise.
Caroline can get up to a high level for a certain length of time, but she can lose it just as quickly because of a lack of training. That's the situation with her illness. Something almost always happened this year, but when she's been able to practice for 2-3 consecutive weeks, she's played good tennis.
Now she and (husband) David (Lee) are travelling around in Europe a bit, and then we'll all sit down and talk about the future." Wozniacki doesn't seem to be willing to retire anytime soon but her season was not definitely the best possible one. She lost to Naomi Osaka in the Beijing China Open semifinals, which was her last match of the season.
