Monday 23 November at 08:01 : Nov.23 (GMM) Christian Klien has revealed that he cannot sign on with Peugeot to contest the 2010 Le Mans 24 hour race until it is clear he has not secured a seat on the formula one grid.

The 26-year-old Austrian, who this year was BMW-Sauber's reserve driver, is hoping to return to racing in 2010 to add to his tally of 48 grands prix.

When asked about the possibility of another Le Mans outing with Peugeot next June, Klien said: "At the moment I am focusing all my options on F1.

"Therefore, right now I cannot commit to Peugeot for Le Mans 2010 because of the June 13 date conflict with the Canadian grand prix."

Klien's best chance of a race seat next year are reportedly with the Qadbak-owned Sauber team, as well as the new entrants Manor, USF1 and Lotus.
