May 4 (GMM) Ferrari and Renault are moving to acquire the services of Polish formula one race driver Robert Kubica.

The 23-year-old has been a star of the 2008 season so far for BMW-Sauber, and is currently third in the drivers' championship classification.

The German newspaper Bild am Sonntag quotes F1 chief executive Bernie Ecclestone as saying: "If I was a team boss, I would pick him."

Bild claims that officials both for Renault and Ferrari have made enquiries as to how long Kubica, who has outqualified his German teammate Nick Heidfeld on every occasion so far this season, is under contract to BMW.

It is understood that he is committed to the Munich manufacturer only until 2009, whereafter an option to extend the deal can only be made by mutual consent.
