How can McLaren win constructors' title in Baku?

McLaren are on their way to winning back-to-back constructors' championships and could mathematically seal the title as early as Sunday's race in Azerbaijan.

To be crowned champions for a 10th time - and with seven races still to go - McLaren need to outscore second-placed Ferrari by nine points in Baku, while not being outscored by Mercedes by 12 points or more, and Red Bull by 33 points or more.

McLaren are 337 points ahead of Ferrari after finishing second and third at Monza
