Paulinho enjoyed a winning debut for Barcelona at Alaves on Saturday.
The midfielder came on in the 88th minute for Andres Iniesta, wearing the No 15 shirt.
"I should keep working and get to know my team-mates to enter into the team bit by bit."
On the game he added: "Alaves played on the counter, tight at the back, looking to come out with speed after a lost ball or when they won it back."
On Barcelona: "I think the team's doing well, calmly, securely, playing with patience, without haste. The truth is we got a result we deserved."
