Sergio Perez has said that Felipe Massa was to blame for their crash on the last lap of the Canadian Grand Prix.
The Force India driver was handed a five-place grid penalty for the Austrian Grand Prix later this month for causing a crash with Massa after the race stewards ruled that he had changed his racing line heading into the corner.
The Mexican told Sky Sports News: "It was very disappointing to lose such a strong result through no fault of our own. I was following the same line and braking patterns as in the previous laps and I just got hit from behind by Massa.
"There was plenty of space on the left of my car to attempt a clean overtake and I cannot understand why he had to scrape by.
"I watched several replays of the incident and I can't help but notice how Felipe turns right just before he hits me. I can only think he must have changed his mind and wanted to rejoin the racing line, his misjudgement cost us a big amount of points."
Red Bull's Daniel Ricciardo went on to win the race.
