Barcelona coach Ernesto Valverde is happy with the arrival of Paulinho.
The former Guangzhou Evergrande midfielder joined Barca on Monday just hours after their Supercopa defeat to Real Madrid.
"Paulinho is an important player in the Brazil national team," he pointed out.
"From a technical point of view, he is an important player and he is also physically strong.
"He can give us another dimension, as there's no other player like him in the squad."
