Jul.17 (GMM) Robert Kubica this week is still giving nothing away about the identity of his formula one employer for the 2009 season.

The Pole's shining form for the BMW-Sauber team this season has undoubtedly impressed many influential residents of the F1 paddock.

"I am happy with the team," the 23-year-old told the Spanish newspaper Diario AS.

"Will I continue with them? I don't know. It is a difficult question," Kubica explained at the Jarama circuit in Spain, for a team sponsor event.

He played down his recent suggestion that he would like to be partnered with former double world champion and friend Fernando Alonso at the Hinwil based team next year.

"I have never had any problems with my teammates and it would be the same if Alonso was next to me.

"But I don't know whether or not he is coming here, I still do not know even if I will be staying," Kubica added.
