SAKHIR, Bahrain - Christian Horner rejected any doubt about his future as Red Bull team chief on March 2 after watching Max Verstappen lead Sergio Perez home in a resounding one-two success at the season-opening Bahrain Grand Prix.

The 50-year-old Briton, who has guided Red Bull to six constructors’ championship wins and seven drivers’ title triumphs since 2005, said their comprehensive success was down to the unity and work of the team.
