Jenson Button is wary that McLaren might not be able to replicate its Sochi performance at this weekend's United States Grand Prix.

McLaren was competitive all weekend in Russia, culminating in both cars finishing in the top five with Button fourth ahead of team-mate Kevin Magnussen. While he has been encouraged by the improved performance, Button warned McLaren can't expect to definitely be as strong in Austin but is hopeful of still being able to challenge the likes of Ferrari and Red Bull.

"It'll be good to get to Austin after the three-week break," Button said. "I really enjoy this circuit; a great mix of a high-speed straight and really fast, technical sections to get your teeth into. It's also one of the few circuits that run anti-clockwise, which makes it a little bit more of a challenge.

"Although this is only our third grand prix in Austin, it feels like we've been going there a lot longer. It's testament to the fans, who are fantastic and always provide a great welcome, and it's already a very popular track amongst the drivers.

"I've had positive results there over the past two years, and our performance in recent races has shown that our pace is improving as we move towards the end of the season, so I'm looking forward to this weekend.

"Perhaps this track won't suit us quite as well as Sochi did, but it's a similar circuit in terms of set-up so I'm hopeful we can take the fight to our closest rivals. As usual, we'll be pushing to get the maximum out of our car and secure a strong finish for the team in front of the passionate US fans."
