Malcom has admitted that he is hoping to "learn a lot" from new teammate Lionel Messi after completing a "dream" switch to Barcelona.
The Catalan giants hijacked Roma's move for the Brazilian winger earlier this week for a fee north of £37m, making him their third signing of the summer window following the arrivals of Clement Lenglet and Arthur.
Speaking at his unveiling at Nike's Portland HQ, the 21-year-old - also reportedly a target for Tottenham Hotspur, Everton and Chelsea - said that he is hoping to follow in the footsteps of some of the world's greatest players, particularly those of Brazilian heritage.
"I know it's a challenge to play for FC Barcelona, but this is a dream I've had since I was little," he told the assembled press. "I'm a forward, and I'm multi-faceted, good in one-on-one situations, I'm very fast, and I can help out defensively.
"Messi is the best player in the world. He's a legend. And I hope to learn a lot from him.
Malcom, yet to be capped at senior level by Brazil, scored 20 goals in 84 Ligue 1 appearances for Bordeaux.
