British racer Jenson Button hints he may leave Formula One

The BBC quoted Jenson Button, as saying that being unsure about one's future opens your eyes to different challenges and possibilities.

Button, 34, has had talks with Porsche about moving to endurance racing next season, a move former F1 driver Mark Webber made at the end of 2013.

McLaren are leaning towards retaining Magnussen, who is in his debut season this year, and it is understood that even if the team were to ask Button to stay, he may turn them down.

Sources close to Button, who has driven for McLaren for five years, say he has not been impressed by the way the team have handled the situation regarding their future driver line-up.

He said he could not comment on whether he would stay at McLaren for the 2015-16 season even if the latter asked him to and added that he was excited about the challenges ahead and had a lot of different ideas for his future.
