Nico Rosberg, the former Mercedes driver and Sky F1 pundit, believes Christian Horner’s sacking by Red Bull was “a long time in the making.” And the 2016 World Champion says it feels “completely unreal” to think that Horner is no longer in charge of the team he built into a winning machine.

Christian Horner was sacked as team principal of Red Bull Racing in July, ending his 20-year spell in charge. No clear explanation has been provided by Red Bull so far, and the announcement of Laurent Mekies as his replacement followed just minutes after the news broke.
