Drivers' Championship Review
Lewis Hamilton extended his lead in the championship following victory at Suzuka, and he now leads his teammate Nico Rosberg by 10 points.
Daniel Ricciardo, who is in third place will still have hope of catching the two drivers in front, but will have to be wary of his teammate, who is slowly regaining form in the last couple of races.
Sebastian Vettel, has leapfrogged Valteri Bottas and Fernando Alonso into fourth following two consecutive podium finishes in Singapore and Japan. That fight is sure to go down to the last race, with the Williams equally adept at picking up points in the coming races.
Constructors' Championship Review
The Constructors battle is as good as over as another one-two finish in Japan saw the Mercedes team extend the lead and they are now 10 points short having a lead of 200 points over nearest challengers Red Bull.
With Ferrari having a bad weekend at Suzuka, Williams have eked out a 23-point lead to consolidate their third position with Ferrari comfortable in fourth.
The battle for fifth and sixth places is also sure to go down to the wire with Force India currently leading McLaren by just a single point.
