Sergio Marchionne has said that the serene winter pre-season enjoyed so far by Mercedes makes him "worry".
Earlier, the Ferrari president had targeted a winning start for the red team at the forthcoming Melbourne season opener, before Mercedes began dazzling its rivals with lap after lap in Barcelona testing.
"Around the world in four days," Marchionne commented to Italian journalists at the Geneva Motor Show.
He said that Ferrari is also having a good winter, explaining that "power unit and the car are matched well and the drivers are happy, even if there is still work to do.
"I hope we can put it on the front row at the first grand prix.
"I'm hesitating because I see that Mercedes is so calm, and that makes me worry."
The first grand prix of the year will be held in Melbourne on March 20.
