Ferrari team principal Stefano Domenicali says that Kimi Raikkonen has returned to the team as a more mature driver.
Raikkonen is beginning his second stint at Ferrari having raced for the team between 2007 and 2009.
Domenicali believes that Raikkonen is aware of the challenge he faces in the form of team-mate Fernando Alonso.
"I have found a more mature Kimi, more closely knit to the team," said Domenicali.
"He comes to Maranello almost every week to work with the engineers."
"He knows his worth and he knows what team he has returned to and what challenges he will face, having a world champion like Alonso alongside him for whom he has respect and he will have to adapt to working with him."
"Fernando is extremely intelligent and has managed to stay ahead in whatever car he has driven. He has an ability to interpret the race and to read it in an amazing way and I think he will make the most of the new regulations, which will require some stages of the race to be managed in a different way. We feel close to him partly because it was such a long time ago that we decided to invest in him."
Domenicali remains cautiously optimistic with regards to the potential of Ferrari's F14 T.
"In Jerez, we saw the F14 T get off on the right foot, responding well to changes, while the basic data corresponds to the parameters established in the wind tunnel and there were no bad surprises."
"Clearly there is still much to do because it’s impossible to start with a perfect car in a season featuring so many changes. The start of the championship will be full of unknown quantities and it is far too early to make any sort of prediction. I think we will start to understand a bit more only at the last Bahrain test."
"My optimism is based on the fact we know which areas need working on: caution is always a good approach, but that doesn’t mean the people working on this project lack the commitment or the will to show our competitors how well we can do things at Ferrari."
