McLaren driver Jenson Button has reiterated that he is unsure where his future lies next season, but has insisted that he is not finished with the sport.
The 34-year-old is rumoured to have had his final season with McLaren amid reports that Fernando Alonso is poised to join the team following his departure from Ferrari.
In the final race of the season in Abu Dhabi yesterday, Button missed out on a place on the podium, but finished fifth as Mercedes star Lewis Hamilton clinched first to win the championship title.
Today on Twitter, Button wrote: "Whatever happens next year with my career I know I've done all I can on and off the track, it's been a pleasure to call @mclarenf1 my home for the last 5 years.
"A big thank you to all of my supporters over the years and especially the strength that you have given me the past year. I'm not done yet!! There's still so much I want to achieve in this sport #JB22 #Bringtheaction."
The Brit, who won the title in 2009, has spent four years with McLaren.
