My guess as to what will happen in a fortnights time.
Mercedes will find a gremlin in Lewis's car, so Rosberg can win.
German car German driver.
Probably something like stuck wheel at the tyre change or a convenient electrical fault.
They have won the constructors championship so having Lewis finish down the list won't harm them a bit.
Lewis will get peed off,leave Mercedes and in steps Alonzo.
I hope it doesn't happen and Lewis wins,but I am not confident.

Cheers
