“I think Max has really grown up this year,” Horner said. “He is the leader of the team. I think he has taken on that role with a great sense of responsibility.
“For me, Max is the most complete driver in Formula 1. The form that he has demonstrated throughout the year is really of a different level.
“Max has no ego problems, is very accessible and therefore so popular in the garage and with the company.
“You see that everyone wants to take an extra step for him: because they believe in Max and fully support him.
“The hours they all spend in the garage to get all parts on the car and constantly improve it: that is unprecedented.
