Britain's Lewis Hamilton praised the team after winning his fifth Formula One world championship on Sunday at the Mexican Grand Prix. He said, "Mercedes and my team have just been the most incredible unit."
Red Bull's Max Verstappen won the Mexican GP and Hamilton finished fourth while Ferrari rival Sebastian Vettel took second place.
The 33-year-old Hamilton admitted that it was one of his worst races of the year as he came home fourth.
"I don't know if it will ever kick in," said Hamilton. "We have just had a difficult afternoon and it was tough. I didn't know if we would get the car home.
"It has been the toughest year physically, mentally and personally with everything I'm committed to, but I have amazing support.
"Mercedes and my team have just been the most incredible unit and worked to raise the bar. In my mind it is just another day of fighting and I have more races to win, it is not over.
