Sauber driver Nico Hulkenberg has admitted that he does not know where his Formula 1 future lies.
The team have come into financial difficulties this season, but Hulkenberg said that does not mean that he will leave Sauber at the end of the campaign.
"The future is still open, my management and I are looking at all the possible options, including Sauber," he told Sky Sports News.
"Nothing has been decided and we are still quite a way away from making a decision too."
Hulkenberg joined Sauber at the end of last season from Force India.
