Jenson Button insists he is "not done yet" amid uncertainty surrounding his McLaren future.

McLaren will announce their drivers' line-up for the 2015 season on 1 December with either Button or teammate Kevin Magnussen expected to be named Fernando Alonso's teammate ahead of the Spaniard's imminent arrival from Ferrari.

Button, 34, has spoken of his disappointment over the "uncomfortable position" the Woking-based team have put him in but, following the final race of the season at Abu Dhabi, he remains determined to remain in F1.

"Whatever happens next year with my career I know I have done all I can on and off the track, it's been a pleasure to call McLaren my home for the last five years," Button wrote on Twitter.

"A big thank you to all my supporters over the years and especially the strength that you have given me the past year. I am not done yet! There is still so much I want to achieve in this sport."

Button has previously suggested he may not wait until 1 December to learn of McLaren's decision.

"I'm open to many things in life. I love what I do for a living, I love racing in F1, and the time I have spent with McLaren has been great but will I wait for the decision? That's something I can't comment on right now..."

Button finished the 2014 season in eighth place with more than twice as many points as teammate Magnussen.
