MONTMELO, Spain -- All the early signs from the first week of testing suggest Ferrari has stolen a march on its rivals. The Italian team, revitalised under its new team principal Mattia Binotto, not only looked quick on track, it was confident off it. After his first proper taste of the SF90 on Monday, Sebastian Vettel said the opening day of the test had been "unbelievable" and "close to perfection". By the final day, Vettel's new teammate Charles Leclerc was equally buoyant.
