Roger Federer, 3rd World, was not worried Sunday in the round of 16 of the US Open by David Goffin (15th) that he eliminated 6-2, 6-2, 6-0 in 1h19.

"It was great, like the previous game, I had great sensations, but he did not play at his best," said the Swiss, who will face Grigor Dimitrov (78th) in the quarterfinals.

"I am very happy with my level today," he added.

"I found my rhythm, I feel good in my footwork, when I feel calm in my legs when I hit a ball, in the backhand, forehand or volley, that means that I entered my tournament and that's the feeling I had today against Goffin, "he confirmed at a press conference.

The Belgian could only explain his feeling of helplessness.

"I felt good, but when we find ourselves on the court facing him we start to misuse, to miss balls we did not usually miss, we do not really feel good, he do not let play, and behind he makes very good points, so if he is very good and I very bad, the gap is very large ... ", analyzed Goffin.

"He tried to play faster than the light in the first three games, he made a few mistakes and I thought that he would slow down a little more and I would have a bit more rhythm. it is precisely here that I missed and lost the opportunity to put myself at ease in the match, "he regretted.

"In addition, he climbs more and more level of play, he relaxes, he tries more and more, he succeeds and it becomes complicated and it is hard to stay in the game. it rolls out, it's just the punching ball, then we go back (to the locker room), "concluded the Belgian.

Federer, five-time record holder at Flushing Meadows with Pete Sampras and Jimmy Connors, qualified for his 13th quarter-final at the US Open, like Andre Agassi, but still four points behind Connors' record. In total, he will play, at age 38, his 56th quarterfinal Grand Slam, a record.
