Citroen team principal Yves Matton has admitted he could ask Sebastien Loeb to return to the World Rally Championship if the French team falls behind in the manufacturers' race.
Loeb is already scheduled to compete in Argentina and France this season as part of his four-event programme.
But there is a chance he might be called up again towards the end of the year in order to help defend Citroen's manufacturers' title in the face of a strong challenge from Volkswagen.
Asked if he would ask Loeb back, Matton replied: "I think you know it's not my decision. I think he doesn't want to, maybe.
"It's not on my mind for the moment. I have to be happy with what I have already this season: I have my four rallies with him - at the start he was doing nothing this year.
"At the end of the season, if I ask him to do one [extra] rally and with this rally we will be champion, then for sure I will ask.
"I am not panicking, I am confident we can do it. Seb Ogier is showing something incredible, but it's like that. We need to continue to believe and fight."
Citroen leads the manufacturers' championship from VW by six points after last week's Rally Mexico. The Versailles team has won the title eight times in the last 10 years.
