Jolyon Palmer has blamed Romain Grosjean for their first-lap crash in the Russian GP.
Both drivers crashed out of the race as a result of the collision which saw the stricken Haas sent airborne.
The incident was investigated by the Sochi stewards before it was determined that no further action was required.
However, Renault driver Palmer is adamant he did nothing wrong.
"There was no gap," Palmer told Sky F1. "I couldn't give him any more. Maybe he didn't know that but I'm blaming him.
"There was not much l could do. I had a Sauber there."
