Brazilian winger Malcom has completed his £36.5m transfer to Barcelona from Bordeaux.
The deal was first announced on Tuesday after the Spanish champions beat Roma to the signature of the 21-year-old.
Malcom, who scored 20 goals and set up 13 in 84 Ligue 1 games for Bordeaux, will join Barcelona on their USA tour.
He is the club’s second Brazilian summer signing, after midfielder Arthur joined from Gremio for £35.5m.
They have also signed Sevilla centre-back Clement Lenglet for 35.9 million euros (£32m).
