Robert Kubica's management stance baffles Renault chief Eric Boullier

Morelli said the suggestions that Kubica would definitely not make the first race of next year were wrong, and that there was still some hope that he could still be ready - even though it is not certain right now.

In an interview with Gazzetta dello Sport, Morelli said: "I don't understand why Renault has changed Robert's words. It's not true he won't be ready for 2012: he stated he doesn't have certainty that he will be in shape for the first tests in February"

Boullier does not understand why Morelli has adopted such a stance though, because he insists that the press release his team issued earlier this week was approved by Kubica's manager.

"We agreed, because obviously Robert couldn't start the season next year with us, or anybody actually, with Daniele Morelli to make a communication," said Boullier at Interlagos. "So at least we could inform people about what is going on.

"He approved the communication so everything was fine. He approved it, and now he is upset with I don't know what to be honest. I don't want to comment more because it's a waste of time."

Boullier has said that his team remains committed to doing all it can to help Kubica back to F1, even though there is no contract in place for next year and speculation has linked the Polish driver with Ferrari.

"We have been very clear, I think professional," said Boullier. "We have waited for him for a long time and we are still waiting for him if he wants to be testing for us or ready to assess him or help him."

Boullier welcomed the fact that with the Kubica situation at least clear from his perspective, that the team could now focus properly on its driver plans for 2012.

"Yes it's good - now we have the green light to start," he said.
