MotoGP, Championship maths: Marquez wins at Sepang if...

The Phillip Island race changed the face of a championship that had been looking as if it would go to the wire at Valencia. Now it's likely to be decided already at Sepang. Marquez has a very good chance of getting the job done this Sunday, thanks to what is now a 33-point lead over Dovizioso.

For the championship fight to continue as far as Valencia, it won't be enough for Andrea to win or simply finish ahead of Marquez on Sunday, he will also have to hope that other riders finish between him and Marc, otherwise it's game over.

Dovi's chances of bringing the title back to Italy are not so good, but it's also true that the MotoGP can throw up unexpected surprises and the forecast promises continuous rain showers over the Sepang weekend...

We can only wait and see, keeping one eye on the screen and the other on the calculator. Here's a brief overview to help you.
