The 21-year-old has caught the eye of many European clubs with his dazzling performances, including several in Italy.
Sampdoria and Atalanta are particular admirers of Man and are considering approaches for him this summer.
Any move by Atalanta would depend on a player leaving Gian Piero Gasperini’s impressive side.
The 4-cap Romanian international is a left-footer but can play on either flank or as an attacking midfielder.
Steaua’s requests for the player are currently high with the 26-time league champions asking for around €18m.
Man has scored seven goals and delivered four assists in 26 appearances for FCSB this season.
