Jolyon Palmer stated that Felipe Nasr was to blame for the clash early in the Italian Grand Prix that saw them collide, with the Sauber spun out while Palmer's front wing was destroyed by the contact.
"I had a really good start, made up a lot of places, and was trying to pass Nasr," Palmer told Sky Sports F1. "We were side by side through Turn 1, and then he ran me off the road in Turn 2 so we crashed.
"He's not racing very fairly and he ended both of our races," he added. "There's better racing in GP2 and GP3 than that.
"You've got to race fairly, and if you just drive someone off the road when we're side-by-side then the only choice I have is to drive into the gravel or we crash."
Palmer made it back to pit lane for a new front wing but eventually retired from the race with further damage to the Renault.
The British driver was clearly non-plussed by the news that Nasr had been given a ten-second time penalty for causing the incident, especially once the Brazilian also retired from the race making the penalty moot.
"I think he should have a grid drop because he's ended my race," Palmer stated.
Nasr took a different view, saying that he had been ahead going through the corner on lap 3 and that the first he knew about it was when he had felt a big hit on the rear of his car which had spun him out.
"It's not going to change anything now," Nasr sighed. "The race is over for me and for him."
