Neymar, 21, agreed a deal to join the Catalan outfit from Santos this summer, but it has been suggested in some quarters that the Brazilian would struggle in Spain.
That is not a view shared by Pedro, however, with the Spanish winger insisting that Neymar will "adapt very quickly" to life at Camp Nou.
"He will adapt very quickly. It is true that you need an adjustment period to get to know the game in another country: how everything is, the city etc," Pedro told El Mundo Deportivo.
"I think he is also happy and excited about playing for Barca, so hopefully be an important player for us."
Both Pedro and Neymar are currently on Confederations Cup duty in Brazil.
