McLaren racing director Eric Boullier has dismissed suggestions that Jenson Button is driving to save his career in the final three races of this season.

With Honda set to provide engines for the Woking-based outfit from 2015, speculation has been rife about who will compete for the famous marque, with Fernando Alonso widely linked with a return to the constructor.

However, Boullier was quick to cool rumours that the 2009 world champion is on his way out of the team.

Boullier is quoted by Sportal as saying: "We don't need him to deliver an extra job on track to - let's say - save his job. We know the value of Jenson and we know he is a world champion-class driver and he has been a world champion already.

"I'm in charge of McLaren Racing and we have to build the best for the team. Drivers are obviously very important in the discussion and Jenson is more than considered to stay with us for the long term.

"But we are still investigating what we want to do with our driver lineup, once we have all the data in our hands."

The F1 grid are in the midst of a three-week break before heading to Austin for the United States Grand Prix.
