Kimi Raikkonen admitted that Ferrari are well aware that they need to close the gap to this season's front-runners because they are "not stupid".
Ferrari have endured a poor start to the season, with a pair of fourth places for Fernando Alonso in Australia and Malaysia their best performances so far.
Raikkonen is yet to finish higher than seventh place during his second stint at Scuderia, but during an interview with Autosport this week, the Finn maintained that he remains confident that they can still challenge at the front-end of the grid.
"At least on paper [Bahrain] was the hardest track for us but we have some new parts coming and hopefully we improve," Raikkonen told Autosport.
"We know what we have to do. The people are pushing 100 per cent, but it takes time. That's the fact.
"We are not stupid people, we have good things going on.
"Unfortunately right now it's not the prettiest thing when you look at the end of the race, but I have belief in the team that we can turn it around.
"I've been with this team and other teams having a hard time and I'm sure we can get it right."
Despite finishing in 10th place in Bahrain, Rakkonen admitted that he was far more comfortable with the F14 T than he was previously.
"I think we improved the car - it feels nicer," added Raikkonen.
"The feeling is better but obviously the results don't show that.
"We have a lot of work to do and we can only push forward. I'm sure we can be stronger in the next race."
