'S**t' Canada result a Mercedes wake-up call - Wolff

Toto Wolff gave a furious verdict of Mercedes' Canadian Grand Prix, labelling a second and fifth-place finish for Valtteri Bottas and Lewis Hamilton a "shit result". Sebastian Vettel streaked to victory at the Circuit Gilles Villeneuve, a scene of Mercedes dominance in recent years.

Hamilton had won the previous three races in Montreal, taking his tally in Canada to six victories, just one shy of Michael Schumacher's record haul.

However, the reigning champion was well off the pace, with Max Verstappen dominant in practice before Vettel took charge on Saturday and Sunday.

The German's win takes him a point ahead of Hamilton at the top of the drivers' standings.

Mercedes had to make do with their old-spec power units after a "quality issue" shelved their planned upgrade.

Despite that disadvantage - both Ferrari and Renault brought new engines to Montreal - Wolff firmly rejected the notion that Mercedes should have been happy with damage limitation.

"Not at all. It is a shit result for us," said Wolff. "I have to put it like that. It is a strong track for us, but all weekend long we did little mistakes, from the beginning on.

"The only feeling I have is that we have to wake up.

"We fall behind in every aspect. This is a track where we should have maximised points. It was not about performing damage limitation."

Asked if there would be consequences within the Mercedes team, Wolff replied: "Yes, that's necessary. We will look at that internally."
