NEW YORK—Fluent in several languages, Roger Federer and Novak Djokovic often conduct multiple post-match press conferences to accomodate the international media in their native tongues.

The world's top two players, who are two of the best interview subjects in the sport, say they have no interest in talking points during US Open matches.

American CoCo Vandweghe made history on Monday conducting the first US Open mid-match interview with ESPN's Pam Shriver during a changeover of opening-round win over Sloane Stephens.

The second-seeded Federer said while he understands the appeal of added access, he's concerned changeover interviews could intrude on his concentration.

"In the beginning, we didn't have interviews going onto the court. That was already weird, but we got used to that," Federer said after his opening-round victory today. "Who knows moving forward what's going to happen? What I heard is they didn't really go through the ATP, which would be the normal thing to do. I think they went straight to the players. That's not the way to go."

"I understand the idea, but what's too much? What's enough?" Federer added. "All these things. I understand pushing the boundaries and being more accessible. For me, in some ways, I haven't done it in 17 years so why start now? At the same time you might think: Who cares, you know? Honestly, I think I'm pretty relaxed when I'm sitting there at the change of ends. But you don't want it to impact your game and you don't want to look back and think: What a stupid move that was in hindsight. Then you're frustrated about it."

Reigning US Open champion Serena Williams said while mid-match interviews may be the long-term future of tennis, she doesn't see it as part of her immediate future.

"Being a vintage player from Lord knows what decade—and I'm old school, so I don't know if I can say that's something I would do, per se—but I found it quite interesting," Serena said. "Maybe that's the future of tennis, the future of where it's going. You know, hopefully they don't make that mandatory. So we'll see."

The world No. 1 says she sees the benefits of on-court interviews for viewers, but prefers focusing on the moment and keeping her thoughts to herself.

"I think it's great for some viewers. Get in the mind of the athletes," Williams said. "But I also think for me, I'm really focused the whole time. I'm really trying to think about what I want to do. I don't necessarily want to answer questions about anything. I just want to be in that moment and kind of focused. That's kind of the integrity of tennis when you think about it. It's just you on the court. It's not a reporter. It's not a coach. It's just you in that moment. I kind of love that. It's the only sport where you have that."

Djokovic has been an entertaining on-court presence at past US Opens, including his comic impressions of the service motions of Maria Sharapova, Andy Roddick and Rafael Nadal. He also hit with ESPN analyst John McEnroe after one of his matches on Arthur Ashe Stadium a few years back.

The top seed says he understands the entertainment value of the on-court interview, but will not conduct changeover interviews during this year's Open.

"What I think they're trying to do here is kind of implement a same kind of media interaction as in, for example, other sports, like basketball after first or second quarter," Djokovic said. "I don't know how much it can really work in tennis, but I think the impression of this first interview has been made. I think most players in the locker room are talking about. It's going to be interesting to see if somebody is going to follow up and accept to do the same. I will not, definitely, this tournament. But who knows? Who knows what the future brings?"
