Malcom and his Barcelona team-mates are standing by Ousmane Dembele as he comes through a difficult spell at Camp Nou.
Dembele has not started a match in La Liga since September and was left out of Barca’s matchday squad against Real Betis recently, with subsequent reports claiming the club are unhappy with the player’s attitude.
But fellow winger Malcom, who is also 21, says the France international still has the support of his peers in the dressing room.
“[Dembele] is young, but we will support him in all situations to learn,” he told beIN SPORTS.
“I am too. We are supporting him from the dressing room.”
Malcom similarly struggled to make an impact initially after joining the Blaugrana from Bordeaux in July, yet he has no issue with waiting his turn at Camp Nou.
“Nothing is ever easy. Barcelona are the best team in the world,” he said.
“It is difficult.
“There are many players with quality, many who were at the World Cup, and you have to be patient, keep calm. And when there are opportunities, you have to take advantage of them.”
A breakthrough moment came when he netted from the bench against Inter and he added: “Scoring in the Champions League gave me more confidence, strength and desire to continue.
“You have to work and fight until the end. I will not give up.”
Malcom has previously claimed that he is starting to feel more settled at Barca following a high-profile summer switch.
He told the club’s official website: “It’s all like a family. Everybody wants the best for everybody else.
“There are always jokes in the dressing room and in the Barça WhatsApp group that we have too. I’m with the Brazilians most but I get on with everyone.
“The adaptation’s very good. I’m adapting and learning to speak a bit of Spanish. I have classes three times a week. But I am also learning a lot every day from being with my team-mates. When I speak Spanish 100 per cent, I’ll start Catalan classes too”.
