Max Verstappen's mother, Sophie Kumpen, has revealed the personality traits passed on from her that have allowed her son to become a two-time Formula 1 world champion.
While Verstappen's father Jos' career as an F1 driver is well-documented, his mother's racing career has been less publicised.
Racing runs in Kumpen's family too, with both her and her brother competing in the karting circuit from a young age.
It's not only racing that Kumpen shares with her son with the 47-year-old prone to a fiery comment, as demonstrated after she levelled cheating allegations against Sergio Perez in the comments section of a Twitter post last season.
Now we can get a glimpse behind the curtain at what traits Kumpen has passed on to her world champion son.

'Special' Max
"A racer has to be a little selfish to want to win," Kumpen explained in Viaplay's recently released Anatomy of a Champion documentary.
"Outside of karting, I was a real girl.
"But when you made me angry while racing, I could be incredibly aggressive."
Kumpen also explained how Jos Verstappen's aggression rubbed off on his son as he developed as a driver.
"His father had this as well. If you combine all the good things about Jos with all my good qualities, you get to what makes Max so special."
