'Vettel used his killer instinct' – Berger
26 March 2013 – Ex-Formula 1 driver Gerhard Berger says Sebastian Vettel simply did what felt natural to him by ignoring team orders and overtaking Mark Webber for victory in Malaysia, explaining that multiple world titles cannot be achieved without being selfish.
Vettel came under fire following the race and quickly apologised to Red Bull team-mate Webber, but Berger has stated that he was using his 'killer instinct'.
"To win a World Championship three or four times, you have to be very selfish," Berger told BBC Radio 5 live. "These boys have such a big killer instinct. They cannot follow their brain and they just do what their instinct tells them. "This is part of Vettel's success and nobody - no team-mate, no team chief - will change it."
Vettel's Malaysian Grand Prix victory saw him move ahead of Kimi Räikkönen in the championship standings, with the German chasing a fourth successive world title.
