Felipe Massa has pointed an accusing finger at Sergio Perez for an horrific smash that led to both men undergoing hospital checks.

The incident came on the final lap of the Canadian Grand Prix at the Circuit Gilles Villeneuve, with Massa and Perez scrapping over fourth place behind debut race winner Daniel Ricciardo in his Red Bull.

As Massa pulled out from behind Perez to pass, the Mexican made a small move to his left, resulting in the Brazilian in his Williams smashing into the left-rear wheel of the Force India.

It resulted in Perez ramming into a barrier to his right, whereas Massa hurtled straight on into a tyre wall at turn one, suffering a 27g impact, narrowly avoiding the Red Bull of third-placed Sebastian Vettel en route.

Although both men remarkably emerged unscathed from their cars, as a precaution they were initially assessed at the track medical centre, and then airlifted on to hospital.

Both were eventually released after passing tests, but Massa said: “I thought it (the accident) was going to hurt because it was a very strong impact. I’m really happy nothing happened.

“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 turned into somebody under braking. He has done this many times, but he didn’t say anything. He just turned and left.”

Massa was also scathing of the stewards’ decision to only hand Perez a five-place grid penalty for the next race in Austria on June 22.

“I hope he learns because we were doing 300 kilometres per hour at the time,” added Massa.

“It was dangerous and we could have had a very serious accident, so for me the penalty is not enough. We could have crashed into Vettel.”
