Sao Paulo: Jenson Button finished fourth with a smile in Sunday`s Brazilian Grand Prix but admitted he still had no idea if he would still be racing with McLaren next season.
The 34-year-old Briton, who was world champion in 2009, has been unable to confirm any plans for the future while McLaren delay their own decisions on the team`s drive line-up for 2015.
"I enjoyed the race and had a great battle with Kimi (Raikkonen)," said Button.
"To beat both Red Bulls, both Ferraris and a Williams is not a bad day`s work. But that`s all I can do right now -- go out and enjoy my racing."
In the build-up to Sunday`s race, Button struggled in practice and was plagued by questions about his future.
But on Saturday, he qualified fifth on the grid.
"Experience showed today, so I am really happy with fourth place," he told reporters.
"You always want more, to challenge for that podium and we felt that we were sort of playing with the Williams at one point, but it wasn`t the case."
Amid rumours that he is set to be replaced by two-time champion Fernando Alonso of Ferrari, Button said he did not know what McLaren`s plans were.
Asked what his future held, he said: "Not ready to stop racing."
