Nico Rosberg has admitted that he is 'disappointed' with his Williams F1 team, after the Grove-based outfit seemed to pin the blame squarely at his feet for the pit-lane accident in the Canadian Grand Prix a fortnight ago.

In much the same manner as close friend and former karting rival Lewis Hamilton, Rosberg failed to realise the red light was on at the end of the Montreal pit-lane after the field piled into the pits en masse on lap 19, following the appearance of the safety car to clear away Adrian Sutil's stranded Force India.

That error saw Hamilton calamitously run into the back of Kimi Raikkonen's Ferrari - the Finn, like eventual race-winner Robert Kubica, waiting dutifully at the end of the pit-lane before rejoining the track - with the following Rosberg braking hard, but not managing to slow down in time and slewing into the back of the McLaren-Mercedes.

Whilst Hamilton and an aggrieved Raikkonen were out on the spot, Rosberg was able to tour around for another lap before pitting once more to have his nose cone replaced, ultimately going on to take the chequered flag out of the points in a lowly tenth place, having run fourth early on.

Worse still, the race stewards handed both the young German and Hamilton ten-place grid demotions for this weekend's French Grand Prix at Magny-Cours, a significant penalty around a circuit on which it is notoriously difficult to overtake.

In media reports in the wake of the Canadian race, a Williams team member revealed that Rosberg had actually been warned on the radio about the hazard at the end of the pit-lane before he hit the rear of Hamilton's car, and though the 22-year-old accepted responsibility for the error, he did confess that he was unhappy with the way Williams had publicly handled it.

"I am disappointed about the comment," he is quoted as saying by Switzerland's Motorsport Aktuell. "I would have expected that the team would deal with it internally."
