Max Verstappen says he is "relaxed" over his Formula 1 future amid reports that Red Bull will split with Renault and use Honda power units from 2019.
A host of engine-related announcements are expected to be made in the coming days, with Renault, McLaren, Honda, Red Bull and Toro Rosso all involved.
McLaren is set to switch from Honda to Renault power units, with the Japanese manufacturer moving on to power Red Bull junior team Toro Rosso.
Toro Rosso linking up with Honda is seen as a potential route for Red Bull to secure a works engine deal in the future, should significant progress be made.
Meanwhile, reports have circulated, originally from the Daily Mail, that Renault has told Red Bull it wants to terminate their engine agreement at the end of next year.
In theory, this could mean Red Bull having to use Honda's power unit as early as 2019, casting doubt over Verstappen and Daniel Ricciardo's futures.
However, speaking to media in the Marina Bay paddock on Thursday, the Dutchman described himself as "not too stressed" about the situation.
"I'm pretty relaxed about it," stated Verstappen, on his future.
Asked about the prospect of driving with a Honda engine, he said: "Maybe, but that's 2019, if… and at the end of the day, I'm not making the decision.
"You never know, it [could] be that Honda next year is very competitive, but I don’t know what’s [been] decided for the future.
"I know that I'm driving with a Red Bull-Renault next year, and then we'll see."
Verstappen insisted that his focus is on fighting for the championship with Red Bull in 2018.
"That's what I want and hopefully we will have it next year," he commented, when asked about securing a potential title-winning car.
"I want to focus on the beginning of 2018 and see where we are."
