LONDON, England - Red Bull team boss Christian Horner has defended Sebastian Vettel, arguing that Mark Webber has also ignored team orders and that champions do not succeed by being submissive.Following the "Multi-21" team orders affair at the 2013 Malaysian GP, Red Bull is still dealing with the fall-out of the now apparently broken relationship between its drivers.After the 2013 Sepang race, s furious Webber was heard saying little to his German team mate except 'Multi-21' - a code apparently meaning "hold station".OTHERS WOULD IGNORE ORDERSHorner told Sky News: "Multi-21 means car 2 ahead of car 1; Multi-12 means car 1 ahead of car 2.
