Unai Emery is looking for reinforcements in January and Malcom is a target. The Express say the Brazilian would fill a hole at Arsenal and the Gunners wanted to buy him even when he was at Bordeaux.
The story says after Danny Welbeck's injury, the London club have intensified their search for a wide forward. Malcom has only had 296 minutes at Barcelona after they bought him for 41m euros in the summer.
The 21-year-old has also been linked to Guangzhou Evergrande, where Paulinho is. Arsenal are also said to be interested in Ousmane Dembele.
The head of recruitment at Arsenal, Sven Mislintat, recently praised the French winger whom he knew at Borussia Dortmund.
