Weeks after the firing of team principal Christian Horner, Red Bull is still dealing with his departure within the team.

Red Bull Formula 1 chief engineer Paul Monaghan has admitted Christian Horner’s sacking was a “shock”, and acknowledged boosting the squad's fortunes would be tough for new CEO Laurent Mekies.

A new Red Bull era begins under Mekies at this weekend’s Belgian Grand Prix. He was appointed after 18 months at Racing Bulls.

Laurent Mekies spoke to the worlds media on Friday for the first time since replacing Christian Horner as Red Bull team principal and chief executive; watch the Belgian GP Sprint on Saturday from 11am,
