Analyzing his loss to Borna Coric at the Shanghai Masters last month, Roger Federer had said: 'He didn't give me many chances on his serve, and for me to stay with him, I should have maybe done a better job on my own serve. But then again, it wasn't bad either, you know. And then in the rallies, like I said, I thought he had more punch than me. Maybe it's a lot of tennis this week, but, you know, quite honestly I'm happy how I'm playing. Laver Cup was good. This was a good week again. I'm happy about my reaction after the US Open.
