Forest sees Hadj Moussa as a potential replacement for Morgan Gibbs-White, while Monaco is preparing to say goodbye to Maghnes Akliouche.
Hadj Moussa joined Feyenoord last summer for a cool €3m, after making waves at Vitesse on loan. Feyenoord is now seeking at least €12m for the talented forward.
This season, Hadj Moussa has been on fire, scoring six Eredivisie goals and dishing out two assists. In the Champions League, he's chipped in with three goals and one assist.
