'Selfish streak' key to Vettel dominance, says former F1 star

Sebastian Vettel’s blatant disregard for team orders during yesterday’s Malaysian Grand Prix was an indication of the “extremely selfish” streak the very best drivers need, according to ex-Formula One star Gerhard Berger.

Vettel deliberately ignored instructions from his Red Bull pit bosses by overtaking team-mate and race leader Mark Webber on lap 46 at Sepang before going on to claim the 27th victory of his F1 career.
