Barcelona is prepared to sell Malcom during the January transfer window if they receive an offer of at least €41 million ($47 million).
Barcelona paid €41 million for Malcom last summer.
Malcom was set to join Serie A side Roma from Bordeaux until Barca swooped in with an eleventh-hour bid.
Ernesto Valverde, however, didn't want the player.
Malcom has made just 10 appearances in all competitions, with six of them coming as a substitute.
