Hamilton needs to finish within 16 points of Vettel in Mexico City to take the 2017 title with two races to spare.
That means:
Hamilton is world champion if he finishes fifth or higher
If Vettel finishes second, Hamilton is world champion if he finishes ninth or higher
If Vettel is third or lower, Hamilton will be world champion
