The forward will join the Spanish champions next season and Scolari feels that the player will adapt to European football quickly following his performance in their 4-2 victory over Italy at the Confederations Cup on Saturday.
"He dealt well with the European marking [against Italy] and Barcelona must be very happy as he is putting a good run of matches together," Scolari told FIFA.com.
"Neymar is a quality player and we knew he had those qualities - but he can still progress. He is an idol for all Brazilians, those who love football. You can call a genius someone who makes a difference and understands what is going on during a match.
"He was doing that before when he was not scoring but was making chances for his teammates and in so doing he was a team player."
Neymar has scored a goal in each of his three appearances at the Confederations
