Barcelona fullback Daniel Alves has confirmed tension inside the locker room. Alves insists such "tiffs" are "inevitable".

"It's inevitable," the Brazilian told Globosporte. "Life within the dressing room is worse than family life. We share more time together with the squad than we do with our own families; if, at times, with members of our own family - our own flesh and blood, we go through problems, imagine what it's like within a dressing room.

"You can't avoid it; problems arise because we are all competitive and all of us want to win and when you want to win, you're leaving yourself open to conflicts."
