Mercedes driver Nico Rosberg has devised a unique solution to prevent sweat dripping into his eyes while driving in this weekend’s Malaysian Grand Prix.

The 56-lap race around the Sepang circuit on the outskirts of Kuala Lumpur is one of the hottest and most humid on the calendar and it is not uncommon for drivers to lose as much as four kilogrammes of weight in sweat over the course of the one-and-a-half-hour race.
