"I feel good. It's nice for me be here with these players, this tournament, and of course playing a Grand Slam. Today I play good tennis again. But I'm really enjoying this week. I met with all the players, especially the top‑10 players. They support me when I was very bad. So now I face to face with them and I say thank you.
I know the way to be with good ranking again. But it's a long road. I need to work very hard because all the players are very tough at this moment. All players playing good tennis, especially here in the five‑set matches. But I'm still improving my game. I feel good with my wrist. That's important to training every day and to feel comfortable for the next tournaments"
