Lotus team boss Eric Boullier says they're doing everything possible in order to keep Kimi Raikkonen with the team for 2014.
Raikkonen has been strongly linked with a move to Red Bull in place of the departing Mark Webber next year, but Boullier feels Lotus still has a lot to offer the Finn.
"It's clear that Lotus F1 Team is a desirable place to be and we know there's been a lot of talk about Kimi's future," he said.
"We all know that Kimi is an individual and he will make his decision in his own time.
"Naturally, we want him to continue in the sport and continue with Lotus F1 Team so we're doing everything we can do to make that happen.
"Romain [also] did a fantastic job in Germany which showed he is capable of mixing it with the very best in the sport."
It's important for Lotus to keep their focus firmly on the current season, however, and with podium finishes for both Raikkonen and Grosjean in Germany a few weeks ago, the team is feeling confident ahead of Hungary.
"It's clear that we've had some good weekends and some weekends which have fallen short of expectations," said Boullier. "Our last outing in Germany clearly falls into the former camp and that's the sort of weekend we want to have in the coming races to get our championship fight back on track. If we can continue that push and refine the car we should be well placed for the second half of the season.
"I think the only place where the car hasn't worked well is in Canada, which can be attributed to cooler temperatures and the energy that circuit puts through the tyres. Elsewhere, we've certainly had the potential for good results so there is no sense of panic.
"Germany showed what can happen when everything goes well and seeing both drivers on the podium - especially when both were fighting for the race win at different points of the race - was especially rewarding."
