Among the sport's talking points is the news that Max Verstappen will become the youngest ever F1 driver when he makes his debut at the age of 17 in next year's championship. Meanwhile, drivers Alexander Rossi and Andre Lotterer are set for F1 debuts of their own in Spa, where Frenchman Romain Grosjean needs to find some form.

Here are five things to know ahead of Friday's first practice session:

Former Brazil striker Fred warned on Thursday that he and his Fluminense teammates might not play this weekend following threatening behavior by fans after the team's recent run of defeats.
