According to one article posted above, FCA rebuffed several overtures (not previously disclosed) by PSA. In the article you just posted, the deal between Renault and FCA fell apart, but if it could be made to work in the future for all parties they would be interested again according to Senard. So everybody is looking for a dancing partner, but they haven't found the right song to bring them together. So the beat goes on, one could say?
As I've said multiple times, there are always discussions that go on behind closed doors, most of which is not meant for public consumption. Everybody is and should be looking for ways to make their company better, and mergers/acquisitions are only a part of that.
