Rio Haryanto is unsure whether he will see out his debut Formula One season with Manor due to issues with his funding.

Haryanto claimed the final spot on the grid ahead of 2016, bringing with him significant financial backing from his native Indonesia. There have recently been reports of Indonesians being encouraged to keep Haryanto on the grid through SMS donations as he cannot finance an entire season.

When pressed on that topic by the official F1 website, Haryanto replied: "I have no answer for that right now. I will give my best and of course the funds are an issue - but this is handled by my management so that I can fully concentrate on racing.

"Actually the question with the funds is not within my hands -- I just want to deliver on track to make me a good candidate. No question, I would like to stay and finish the season here."

Despite that lingering uncertainty over his future Haryanto is not making contingency plans just yet, with his focus solely on the task at hand with Manor.

"Points would be magical - of course. I think the car has improved a lot compared to last year, so that on one or other occasion - when things go wrong for others - we should have a chance. Scoring points... that would just be like winning! And Plan B... no, if you are in F1 you enjoy it, do the best you can - and have a plan later!"
