In a press conference Roger Federer said: “I just felt like [the court] was slow. I couldn't really have any impact. He was doing a good job of returning me... I wasn't hitting my spots, and he was reading my serve, or he was just doing a good job.
I just struggled. As my legs weren't moving, it's hard to see the short ball. In defence, you're weak. The next thing you know you're struggling. That's what I had going."
