“It was a very difficult week, tough week. I’m very happy about today’s match,” he said after his match.

“It was very tough mentally. Had such an amazing run here, and I tried to do my best today. We both were quite tired from yesterday. We both felt a lot of tension, but I’m very glad about the level I played today, especially in the important moments.”
