Rosenior, 41, has been without a club since Chelsea dismissed him in late April, having been brought in from sister club RC Strasbourg earlier in the year following the sacking of Enzo Maresca. His spell at Stamford Bridge was unsuccessful, and Xabi Alonso subsequently took the job on a permanent basis.
Since his departure from Chelsea, Rosenior had been linked with a return to Ligue 1 but turned down an approach from OGC Nice before Paris FC emerged as a serious option. Foot Mercato first reported his interest in the role several weeks ago and now indicates a deal is close.
Paris FC, who finished 11th in their first Ligue 1 season following significant recent investment, represent a project with ambition. The club stepped up to France's top flight after building steadily in recent years and are looking for a head coach who can continue that upward trajectory.
Rosenior has previously managed Hull City in addition to his spells at Strasbourg and Chelsea, giving him experience across English and French football that fits the profile Paris FC are seeking.
The Paris FC appointment, if confirmed, would represent a return to the same league in which Rosenior made his early managerial reputation at Strasbourg before Chelsea came calling. The familiarity with French football and the style of play required in Ligue 1 may work in his favour as he looks to rebuild his reputation after the difficult Chelsea spell.
Paris FC's ambitions beyond the 11th-place finish of their debut top-flight campaign are the incentive. The club has invested significantly to reach this point, and the next step is consolidating at the top level — a challenge that suits a manager keen to prove himself after the disappointment of his Premier League tenure.
