Christian Horner was relieved of his duties as Red Bull Racing team principal and chief executive last week after 20 years in charge of the F1 team and 14 titles

Martin Brundle believes Christian Horner’s singular focus on Max Verstappen during his tenure as Red Bull team principal damaged the team.

Martin Brundle, the Sky F1 pundit, has claimed that Max Verstappen’s entourage “played a key role” in the sacking of Christian Horner as Red Bull team principal. Horner was ‘released’ from his duties last week after more than 20 years in charge, with Racing Bulls boss Laurent Mekies stepping up as his successor.
