Romain Grosjean is in no hurry to decide his future despite Lotus wanting him to commit to the team.
With Pastor Maldonado already confirmed for next season, Lotus have expressed a desire to hold onto both drivers.
"Romain has been part of the Lotus F1 Team family for many years, even since his GP2 days," Lotus deputy team principal Federico Gastaldi said.
"Let's be honest, Romain as a top, top driver is not happy with the 2014 season and this is mirrored by everyone at the team of course."
He added: "All I can say is that it's certainly the intention for Romain to stay at Enstone and continue what has been a great partnership and working relationship."
But while Lotus are ready to commit to the Frenchman, he is still looking at what may be available.
Asked by ESPN how long he plans to take before making a decision, Grosjean said. "As long as options are open!"
That, however, does not mean he is saying no to Lotus.
He added: "They don't really have to convince me, I know what they are capable of doing.
"I know they have made good cars in the past and I know the struggle we have now since we are in the process of understanding what is not working very well between the wind-tunnel and the car and where we can improve.
"I know they are capable of making a good car if they have a budget they can work with that and if they get a good engine, which I believe, hopefully, they will. From there you can assess what they are capable of doing.
"I know the team is not going to do a season like this year next year because they will react and get better. Even though it's not going to be as good a car as last year it's hopefully going to be a car capable of fighting for points much more often, it can still be a good team."
