Ferrari team principal Maurizio Arrivabene says Sebastian Vettel's victory at the Hungarian Grand Prix should be enough to silence the team's doubters.
Pressure in the Italian media has been building on Ferrari at recent races as Williams appeared to take the upper hand in the battle to be best of the rest behind Mercedes. In Hungary, the team achieved its pre-season target of two victories this year and Arrivabene was impressed by the way it conducted itself over the three days of practice, qualifying and the race.
"Until last week they were talking about us as a disaster," Arrivabene said. "Most probably they are not able to read the numbers, or they don't want to read the numbers.
"Yes, we have two victories but we have to keep our feet on the ground and work hard, as has happened this weekend. On Friday we were struggling a lot and at one stage James Allison said to me, 'If I have to think of the worst day of my career, then today is the worst!' But we put together everything, we were working with determination and this is something that tells you everything about this team that is getting together better and better and better.
"They were using the FP3 to try to adjust the car and after that on Saturday evening we thought, 'okay, we are in a better way'. We were not at all thinking about scoring this result, but at least thinking we are in a good way."
Ferrari had the potential to score its first one-two victory since the German Grand Prix in 2010, but Kimi Raikkonen's car suffered an MGU-K failure while running in second place.
"I'm really disappointed because, to be honest, Kimi was really good today - both of them were, especially at the start. This is Formula One and sometimes these things happen. Sometimes you win because the other team scores an own goal, but it's part of the game. We have to accept this.
"Again, congratulations to Kimi for what he did today, but unfortunately something happened and we didn't have the double. It will be a good occasion to have it in the future, so it's another challenge."
