French club Amiens are keen to sign Nathan on loan from Chelsea ahead of Thursday’s transfer deadline.
The Brazilian midfielder, 21, has spent the past two seasons on loan in the Netherlands with Vitesse Arnhem, having joined Chelsea from Atletico Paranaense in 2015.
Several clubs have expressed an interest in signing him on loan for this season, and Amiens, newly promoted to France’s top flight, are hoping to snap him up.
Nathan enjoyed success with Vitesse last season, making 32 appearances, scoring five goals and helping them win the Dutch Cup.
