Suzuka: Formula One world champion Sebastian Vettel said on Saturday that his shock decision to leave Red Bull at the end of the season had come from the heart, denying that he was "running away."
The German told reporters ahead of the Japanese Grand Prix that he was close to signing for a new team, widely expected to be Ferrari.
"I don't have anything I can confirm now," said Vettel, who won the last four world titles with Red Bull in a period of spell-binding dominance. "For now I can't say much. It shouldn't be too long."
