(GMM) Renault boss Eric Boullier is confident Robert Kubica will not switch to a rival team at the end of 2010.
Amid rumors linking the Pole with a move for 2011 to Ferrari, and his standout performance in Monaco, Renault team owner Gerard Lopez said last weekend that the 25-year-old has an opportunity to have "a team built around him".
And the Enstone based team's principal Boullier is quoted by Auto Hebdo: "The ambitions we have and the changes we are making to the car should convince him to stay with us."
However, it has been reported that Kubica has signed an "option" with Ferrari regarding the 2011 season.
Subsequent reports said he will be free to sign with the Maranello based team if Renault is not at least fourth in the constructors' world championship by July 15.
Renault is currently fifth, 13 points behind Mercedes.
