Jolyon Palmer has said that he is not worried about rumours Renault might oust him before the end of the 2016 season.
The French marque's new works team is actively promoting the young careers of Russian-backed Sergey Sirotkin as well as French youngster Esteban Ocon.
Ocon will even drive Palmer's yellow car in Friday practice in Spain, but the British rookie said that he is not worried.
"Honestly, I have no idea where these rumours come from, but they don't bother me at all. I have a contract until the end of the season," said the 2014 GP2 champion.
"Even in Bahrain I heard talk about it, and that was after a good race in Melbourne. But the team told me that everything is fine so I'm totally focused on my work."
Palmer has yet to get any points on the board in the 2016 championship.
