Red Bull team principal Christian Horner has said he believes former F1 Race Director Michael Masi was removed due to pressure from Mercedes, accusing the rival team of "bullying."
Masi botched the finish of the title decider between Red Bull's Max Verstappen and Mercedes' Lewis Hamilton last year. The race was settled by a one-lap sprint, which saw Verstappen pass Hamilton to win the title after the safety car restart rules were incorrectly applied by Masi.
Masi's position has since been replaced by an overhauled system of controlling and officiating F1 races.
"Was it right to fire him based on pressure that was placed on him from a rival team?
