Intro:

Post-match analysis from Roger Federer and Marin Čilić after the duo book their places in the US Open quarter-finals.

Script:

SOUNDBITE (English) Roger Federer:

"I felt like, I mean, I had maybe some margin. I don't know if that was something I was trying to tell myself. He hasn't got the biggest game but he's consistent. He's fast. He can adapt. So he's got things that can make you feel uncomfortable, I must say. He can absorb pace well. From that standpoint, even though I did feel I had margin, because I never played him before, I was still pushing forward all along and trying to always keep a gap between him and me in terms of the result and the scoreline. I was very happy when the match was over, because like this I know. It's done. Next time I play him I know what to expect. Not like today."

SOUNDBITE (English) Marin Cilic:

"Second time in my career that I played, that I'm going to be in the quarter-final for two straight majors. The first was 2009 over here, and then Australia 2010. It shows me that I'm really playing well, and especially at these big tournaments I'm improving. Over here I always played in US Open very well. This year I feel I'm playing good, and I'm going to enjoy the moment."
