Fernando Alonso has once again vented his frustration at Honda following the Canadian Grand Prix after the Spaniard retired from the race two laps from the end. Alonso was running in tenth and was in a position to score the team's first point of the season.

It was a familiar scene watching him clamber out of his car, as the Honda engine has been giving him trouble all season. The Japanese manufacturer has failed to deliver on a promise to upgrade its woefully unreliable and underperforming power unit.

"After 16 years, it doesn't change my life to win a point or not, but we have to start scoring for the work that the mechanics do day and night, changing many engines," the double world champion said.

"I do not have information about the improvement of the engine. I do not work for Honda and I'm not an engine designer. I am of course frustrated, but especially at this time for McLaren, who always give me a top car which is then attacked by everyone on the straight."
