Red Bull have asked other Formula One teams to allow them to use Austrian Christian Klien as a Friday third driver despite the fact that he is not eligible under current rules. "We are asking the other teams to see whether it could be an option," a team spokesman said yesterday. "There has been no outcome yet." The third car role was filled in the first three grands prix of the season by Italian Vitantonio Liuzzi, who has now taken Klien's place as a race driver for the next three races starting with San Marino on April 24. The swap has left Klien, who drove for Jaguar last year, without a role because Friday third car drivers are not allowed to have competed in more than six grands prix in the previous two years.
