McLaren racing director Eric Boullier says the team is not yet thinking about its 2017 driver line-up as it could create a "distraction".
Fernando Alonso is contracted until 2017 but Jenson Button, whose deal expires at the end of the season, has recently been linked to a return to Williams, where his F1 career started in 2000. However Boullier insists next year's line-up is not an immediate concern.
"No, absolutely nothing," Boullier said when asked if the team had discussions around next year. "We have not started discussing anything with any drivers. It's too early in the season so it would be too distracting for the team."
When asked whether he wanted to keep the current line-up on their toes by not entering talks, he replied: "Exactly. It's part of the game."
McLaren's line-up looks set to dominate the driver market speculation again this season, with Button's future the subject of much debate in 2014 and 2015. He was retained for another year on both occasions but this time around McLaren has the highly-rated Stoffel Vandoorne waiting in the wings.
Button was coy over the issue when asked about it during the Monaco Grand Prix weekend.
"I have not thought about the Canadian Grand Prix yet let alone next year," he said on the subject. "That's all I have for you."
