Romain Grosjean has admitted that he faces a difficult challenge in preparing for the Chinese Grand Prix.
The Frenchman and teammate Pastor Maldonado have failed to score points so far this season, but Grosjean is optimistic that he will enjoy better fortune in Shanghai next weekend.
However, the Lotus driver believes that finding the right setup may be tougher to do.
He is quoted by Crash.net as saying: "In the race, things didn't quite work out the way we wanted, but there are still a lot of good positives we take to the next races and, when it all comes together, it's going to be very nice.
"[Shanghai] is quite a particular circuit, where it is not always easy to find the right setup and the temperature can also be cold, so it's quite difficult to predict.
"You never know what to expect, except that there will be a monster traffic jam to get to the circuit!"
Grosjean scored eight points during the 2014 season.
