Daniel Ricciardo believes it is too soon for him to decide his future in Formula One following Red Bull's move to re-sign his younger team-mate Dutchman Max Verstappen.
The Australian, whose current deal runs to 2018, said: "To be honest, it's not that I've said no to anything. It's just still quite early, I think.
"People talked a little bit about contracts and the silly season for next year, but I thought it would still happen next year," he said, speaking during qualifying for the US Grand Prix in Austin, Texas.
Ricciardo, 28, said 20-year-old Verstappen's deal was a positive development.
"Obviously it's not really got anything to do with me, but if I'm to try and extract some positives out of his news it's that it gives us good confidence for next year.
"He and his management see a lot of positives in the team to continue like that.
"I'm 100 percent here next year, I can at least say that, and I think it gives both of us confidence that we'll keep progressing the way we are."
