Lewis Hamilton's struggles on his Ferrari race debut have prompted a brutally honest response from the team principal.
The seven-time Formula 1 world champion was in action for the first time with his new team at last weekend's season-opening Australian Grand Prix following his sensational switch from Mercedes.
But it turned out to be a weekend to forget for the 40-year-old, who finished an incident-packed race down in 10th, two places behind team-mate Charles Leclerc.

Vasseur makes brutal admission over Ferrari failure
Hamilton has made no secret of his desire to challenge for the title having endured several years of frustration at Mercedes, but has admitted he will take some time to get to grips with his new car and surroundings.
That, in addition to the team's decision to keep him out on slick tyres amid treacherous conditions, ensured it was a disappointing start to Hamilton's career at the Scuderia.
Speaking post-race, team principal Fred Vasseur made it clear that the team must learn from their mistakes and make big improvements ahead of this week's Chinese Grand Prix.

"It was the first race, the first time that we have to communicate between the pit wall and the car, and we can do a better job and know each other more," Vasseur said.
"For sure it was not a clean one at all, the strategy was difficult and we need to find a better way to communicate between the car and the pit wall but we will learn from Race 1 and it is not an issue.
"It was not a shock but for sure it was not a good weekend for us. But we focus on next week [the Chinese Grand Prix] and learn a lot from this weekend because we made mistakes.
"We need to improve the communication, understand what Lewis needs from the communication, and it is only in this situation that we can be in the situation. We will be much better next week."
