McLaren may have endured a torrid Formula One season due to struggles with their Honda power units, but Jenson Button believes they can be competitive in 2016.
Button and team-mate Fernando Alonso have only taken 27 points between them from the 17 races in 2015, while they have retired on 12 occasions.
Only Marussia have performed worse than McLaren - who have been constructors' champions eight times - leaving the British-based team ninth in the standings.
Button has claimed 16 of their points this season, including a sixth-placed finish at the United States Grand Prix, and is confident there are more positive times ahead.
"I think we're doing a very good job, we're getting the best out of what we have, I think maximising the potential of what we have at the moment," he said ahead of this weekend's Brazilian Grand Prix.
"Obviously during a season it's very difficult to make changes, but this winter is a very important one for us, to make those big changes and come out a lot stronger next year because we don't want to be where we are, we want to be fighting near the front.
"Whether we can win races or not, that's another question, but I think we can at last fight at the front next year."
Button qualified fifth and finished fourth in Sao Paulo last year.
