Friday 29 January at 08:01 : Jan.29 (GMM) Ferrari may already be working on a 'B' version of its newly launched F10 car.

Britain's Times newspaper referred to rumours "sweeping the Italian media" about the early performance estimates for the new single seater.

The report said it is feared the car is "not as good as the team were hoping for", despite Ferrari having stopped developing the F60 mid last season in order to focus on its successor.

Former Ferrari driver Gerhard Berger told Switzerland's Blick newspaper: "Even with Alonso, Ferrari's overall package is not as strong as it once was with Schumacher.

"They are now missing (Jean) Todt, (Ross) Brawn and the often underestimated designer (Rory) Byrne. And without the right people, soon you are lost," the Austrian added.
