Google Translated:

The four-time champion recently opened up a possibility. Citroën Teamchef Yves Matton came under great pressure after the failed comeback and now seems to be ready to consider his driver's choice. Kris Meeke, Craig Breen and Stephane Lefebvre have a contract for 2018, but the last rallies showed how little the guarantee is for a WRC cockpit, when Andreas Mikkelsen came as a substitute driver for two assignments. Since then, Ogier has been philosophizing publicly about his future, but all doors are now closed in France.

"We have some ideas and know which drivers are on the market," said Matton, "Motorsport aktuell". For reasons of budget, Citroën can only afford another high-caliber, even if the Matton does not want to admit directly. "The only thing I can rule out is that more than one new driver is going to be added." In other words, Ogier, or Mikkelsen.
Maybe someone who knows German can check the article and tell what is actually said?
