Malcom, 21, was on the receiving end from AS Roma star Kostas Manolas before the ICC encounter in the US.
However, the Brazilian netted during the 4-2 defeat to the Italians and displayed what could have been for the Serie A side with a solid display.
However, he refused to let the recent jibes against him affect his settling in period with the LaLiga champions after the controversial transfer debacle.
"I don't get involved with that sort of provocation," Malcom told reporters after the match.
"What's important is what happens on the pitch. There's no need to go over and over [what happened].
"I am here, I'm a Barcelona player and I want to help. I hope to be able to make the supporters happy."
