Williams boss Patrick Head has revealed that he may ask one of his drivers to help the other in the final weeks of the Formula One season.
Juan Pablo Montoya and Ralf Schumacher are still both in title contention with four races remaining.
But Head confirmed that he could ask one to "assist" the other at some point providing that driver had fallen out of championship contention.
"Our agreement with both drivers is clear and accepted by both," said Head.
"They are free to race each other, but not in a manner which puts the team result at risk, until one has no numerical possibility to win the championship.
"Then we request one to assist the other."
Head accepted that the scenario was not ideal, however.
"This is not an ideal position for the team, but it is the basis on which we employ our drivers."
However Head stopped short of saying that Williams would invoke 'team orders', which have been banned in Formula One this season.
