Malcom has said that he 'has no words' to sum up how he feels after scoring for Barcelona on his first home outing for the club.
The £37m summer signing netted Barca's opener in their 3-0 victory over Boca Juniors as they lifted the annual Joan Camper Trophy for a sixth season running.
Malcom beat his man on the edge of the box and fired a low drive under Esteban Andrada in the Boca goal, which Lionel Messi and Rafinha later added to in a one-sided match.
Speaking after the friendly, the 21-year-old admitted that playing alongside Messi made him "very happy".
"I have no words to define it," he told reporters. "Messi is the best in the world and to start a game with him and that he sets you up a goal makes me very happy.
"I'm very happy to be a champion and to see this stadium with so many fans. It's my first game at Camp Nou I have my family in the stands and I scored a goal, it's a dream.
"Although it was a friendly I'm very happy, because it's important to start off scoring. We have great players and I am very happy for how they received me. I hope to score many goals."
Malcom is in contention to start Barcelona's La Liga opener against Alaves on Saturday.
