It would be fair to say Sebastian Vettel is not on the Christmas card list of two of his countrymen and F1 rivals.

Veteran journalist Roger Benoit, long-time correspondent for the Swiss newspaper Blick, travelled to Montreal on the same Zurich flight as Vettel and Mercedes' Nico Rosberg.

He said the pair were seated not a car's length apart, but neither greeted one another nor exchanged a single word.

Benoit said the reason for the freeze was "clear": a few days earlier, Rosberg had said Vettel was definitely to blame for his crash with Red Bull teammate Mark Webber in Turkey.

Meanwhile, after Sunday's Canadian grand prix, 22-year-old Vettel triggered the temper of Force India driver Adrian Sutil.

Vettel, he revealed to the media, had approached the 27-year-old and sarcastically asked if his rearview mirrors had fallen off during the Montreal race.

"He should be quiet. He thinks he's a superstar," Sutil is quoted as retorting.
