Maurizio Arrivabene says that there have been "positive signs" following their staff restructuring earlier this year.
Despite that, Arrivabene is positive going forward.
"Our 2017 [season] began last August with the major change on the technical front" he said. "People expect a lot from Ferrari, wins and success, therefore we will do our utmost to achieve that.
"Ever since the new structure was put in place, with a great engineer like Mattia Binotto in charge, we have seen positive signs, as in Japan and Abu Dhabi" Arrivabene added. "I am not going to make any predictions, but I know the guys are working very hard and all pulling together."
