Wolff: We've grown stronger as a team

Mercedes boss Toto Wolff has revealed that the Silver Arrows have grown stronger as a team this campaign, as they celebrate Lewis Hamilton being crowned world champion for a fifth time.

Hamilton is in his sixth season at Mercedes, and this season they had to fight off more of a challenge than they've had in recent years.

Although it might not seem much of a challenge, with Lewis being crowned champion with two races spare; Sebastian Vettel and Ferrari gave Mercedes a real scare this season.

"We've grown stronger as a team," Mercedes team principal Wolff said when asked what had changed. "The relationships are strong within the team and there's a trust, there's a belief in the strength in the team and particularly in the moments where it has been very difficult.

There was a point in the title race where the lead was swinging between Hamilton and Vettel/Mercedes and Ferrari.

In Austria, Mercedes were dealt their worst day as a constructor since returning in 2010; when Hamilton and his team-mate Valtteri Bottas were both handed DNFs.

"You are not allowed to make mistakes and also to call them out," Wolff continued. "We have a motto which is 'see it, say it, fix it'. And that needs the environment that you are not scared for your job or your role, and (at) the Monday morning briefing after the race, everybody starts with the shortcomings and the mistakes they did on the weekend."
