Jun.9 (GMM/Inautonews.com) Team co-owner Toto Wolff on Friday defended Bruno Senna, after a bad day in Montreal for Williams’ Brazilian driver.

Senna, never higher than 17th quickest on Friday, had several off-track excursions at the Circuit Gilles Villeneuve before crashing heavily at the notorious ‘wall of champions’.

His questionable form threatens to intensify rumours Williams might replace the struggling 28-year-old with reserve driver Valtteri Bottas, who is managed by Austrian Wolff.

Wolff, however, defended Senna, insisting the driver does not need a dressing-down because “he is the one who is the most upset” about the crash.

“What happened to him also happens to many other drivers,” Wolff told Austrian television ORF.

“Of course it’s a pity because the car was severely damaged, but when you are trying to find the limits, these things happen,” he added.

Wolff also said the crash does not mean Senna will have to face the rest of the weekend without Williams’ radical new rear wing.

“We have enough spares,” he said.

Senna was also involved in an incident with Sebastian Vettel on Friday, but it was the world champion who was officially reprimanded by the stewards.

Senna waved a fist at the Red Bull driver after they brushed wheels at high speed on the approach to the final chicane.

On German Sky television, commentator Marc Surer slammed Vettel’s manoeuvre as “dangerous” and “completely unnecessary”.
