Williams' driver Felipe Massa has become involved in a bitter war of words with Sergio Perez following their horrific smash in the Canadian Grand Prix.

The two men blamed each other for the last-lap crash in Sunday’s race.

The stewards ultimately decided that Force India driver Perez was at fault for an incident in which Massa, from the Grove-based team, ran into the back of the Mexican, handing the former a five-place grid penalty for the next race in Austria on June 22.

The crash saw Perez ram into a barrier to his right, while Massa, who was placed fifth at the time, hurtled straight on into a tyre wall, narrowly avoiding the Red Bull of Sebastian Vettel en route.

Both men emerged unscathed from their cars, and were given the all-clear at both the track medical centre and a Montreal hospital after tests.

Massa initially described Perez as “dangerous” and claimed both he and his rival were fortunate to escape injury from such a big hit.

He added: “I spoke to him (Perez) at the medical centre. I was so disappointed with him. I said he needs to learn. I wanted him to put himself in my place because I had a huge crash.

“It’s not the first time he’s turned into somebody under braking. He has done this many times, but he turned and left.”

Perez in turn labelled Williams’s head of vehicle performance Rob Smedley as “clearly misguided”.

Smedley had highlighted Perez’s radio call on lap 67 bemoaning his lack of rear brakes as a reason to have retired the car.

To Smedley, Perez’s words suggested to him the issue was “terminal”, and so should have pulled out.

Perez defended his actions, even suggesting Massa was the guilty party.

He said: “I was following the same line and braking patterns as in the previous laps, and I just got hit from behind by Massa. His misjudgement cost us a big amount of points.”
