Tbh there is quite a lot of info in the Citroen release, both written and in-between the lines:

"Before the start, we asked our drivers to make it to the end of the rally. I don't think we were wrong to think that if they managed to do that, we would end up with two cars in the top five," explained Yves Matton, Citroën Racing Team Principal. "Unfortunately, Kris was unable to adopt the pace required to have an error-free race. After the opening stages, he felt comfortable in the car and said that his pace was consistent with the targets set. Clearly, he has failed to maintain it."
