Malcom has warned Barcelona that he will demand a transfer in January if he does not get more playing time, Mundo Deportivo claims.
The Brazilian winger turned back on a move to Roma at the last minute to join the Catalan side from Bordeaux in the previous transfer window, but has made just two appearances in La Liga, totalling 25 minutes on the field.
Although Malcom, 21, dismissed talk of making an early exit from Camp Nouafter being left out of the squad once again, the Spanish newspaper says he has already issued an ultimatum to the club and could try to force his way out in a few months.
