F1 Today | Horner's new backing and Red Bull's Goodwood crash

Christian Horner is no longer the CEO and team principal of the Red Bull team in Formula 1 after he was sacked last Wednesday.

The Briton has already been replaced by Laurent Mekies, who is stepping up from the Racing Bulls team.

It represents a seismic shift for the Red Bull team as Horner was the only team principal they have had since joining the grid in 2005.

Horner shared a video on Instagram of 10-year-old Teddy paying tribute to the former team principal.

Teddy said: "To my hero Christian Horner. You are the person who inspired me to start watching Formula 1 five years ago. You have been the fire behind the team for the past twenty years and brought so many victories. You will forever have a place in my heart."

Red Bull had a lot of success during the end of the V8 era in Formula 1 as the Austrian team won four consecutive world championships with Sebastian Vettel.

The German was the driver to beat during that time as he got the better of teammate Mark Webber as well as Ferrari and McLaren.

The 2012 car saw Vettel clinch his third world championship after a duel with Alonso and it was driven again last weekend at Goodwood.

The Goodwood Festival of Speed is a famous event where a vast range of cars are driven up the hill, including F1 classics.

Red Bull's sim racing driver Sebastian Job made contact with some hay bales over the weekend in a slow-speed accident.
