Ferrari have made since their disastrous start at the

Ferrari as favourites going into the season opener after a strong pre-season testing and now Vettel has cast doubt over the team's position but believes improvements are coming.
“The last few weeks have been very exhausting for us because we wanted to understand why we did not do as well in Melbourne as we expected,” Vettel said at his press session in Bahrain.
"We are not in a position to make big promises, and Bahrain is another runway.
“But I think we have some ideas in set-up and auto-configuration that should help us to be more competitive again.
“But that's all theoretical, we still have to prove it on the track,” added the German.
