Malcom insisted he wanted to make history with Barcelona after scoring his first goal for the club in the 1-1 Champions League draw against Inter.
The 21-year-old has made just one start in all competitions since arriving in a reported €40million (£36.5m/$48m) deal from Ligue 1 side Bordeaux in the close-season, and his cameo appearance at San Siro was just his fourth for Barca, and first in the Champions League.
Malcom left his mark, however, scoring two minutes after replacing Ousmane Dembele, another young winger who has struggled to nail down a regular starting berth.
