Renault team boss Eric Boullier sets end of October as the latest date to decide if Kubcia can race for his team in 2012.

Eric Boullier: "But in the middle or end of October I need a clear confirmation. My problem is that I cannot miss the opportunity to have Robert back, but at the same time I need to defend the interests of my team. I need to have the best driver lineup I can have, or the best I can afford."
