Coutinho, who joined Barca from Liverpool last month, says despite their star status, he has found all his teammates well grounded.
He told Sport: "It is a very difficult question ... [hesitation]. All the players are very good, I see it every day, in training and in games.
"You see them and think, 'this is incredible', but it is not something that surprised me because when I came I already knew it. What has helped me a lot has been the reception of the locker room: they are all very quiet people."
