Ride on board Nico Rosberg's 2014 Canadian Grand Prix pole lap with Allan McNish describing what it takes to complete a perfect lap of Circuit Gilles Villeneuve.

Despite leading from the start in 2014, an ERS failure for both Mercedes cars caused Lewis Hamilton to retire, and Rosberg slipped to second, handing a shock victory to Red Bull's Daniel Ricciardo.

This year's Canadian Grand Prix will see Rosberg and Hamilton going head-to-head again, and after Rosberg's surprise win in Monaco, Hamilton's lead in the championship has been cut to just 10 points.
