Kimi Raikkonen insists Ferrari is working hard to live up to the lofty expectations set by Sergio Marchionne after the company president declared he wants to see wins soon.

Having expressed disappointment with Ferrari's indifferent start to the 2016 season, Ferrari president Marchionne says he wants to see the team challenging for victories from this weekend's Spanish Grand Prix.

Despite the bold aspirations from the top, Raikkonen - currently third in the overall standings after two podiums from the opening four rounds - says it isn't a critique on the efforts of the Italian team, adding it is pushing to fulfil high expectations across the board.

"Obviously we always try to please our fans, the people and our president," he said. "We always try to do our best in every single race weekend. It's always easy to say afterwards what could have been, but the facts are this is what we have achieved so far. Yes, some of the races haven't been nearly as positive as they could have been but the end result is not lying, they are real.

"For sure we can do a better job, we want to achieve better results, we keep pushing and try to make the best out of every race weekend. The aim is to be in front with the two cars. This is not where we want to be, but I don't think we're as far as some of the results show. We know what has to be done and we're not far away."

Looking ahead to the Spanish Grand Prix weekend, Raikkonen plays down the suggestion that Ferrari is facing a tough season if it cannot challenge Mercedes around the Circuit de Catalunya.

"One race doesn't decide the season. We keep improving the car as any other team does. We see the performance in other races too, we have to perform in every circuit we go to, and if the car is fantastic here that doesn't mean it's going to give us better results in the next race.

"If you look back to history it's fair to say a car that works well here works well in other tracks, but it's not so simple. We had a good winter testing here, but now we have different conditions, it's warmer, so we'll see if the car is good enough - we'll find out."
