You might assume that either Lewis Hamilton or Max Verstappen has the biggest global fanbase of the current crop of Formula 1 stars – but don't rule out Sergio Perez.
Checo is incredibly popular across the Atlantic. Of course, he has the full support of his Mexican homeland and, with no South Americans on the grid, many F1 fans in that part of the world get behind Perez as his birthplace is the closest geographically.
And let's not forget the USA. There's a massive Spanish-speaking community in America and, considering the huge rise in popularity the sport has seen in recent years in that part of the world, it's no surprise that Perez is among the favourites there as well.
