Barcelona senior players confronted coach Ernesto Valverde last week after their shock Champions League elimination by Roma.
Sport says Barca players believe Valverde's team selection was wrong for the second-leg and told him as much in the away locker room after the defeat.
"Mister, it was a game for physical players," said one heavyweight.
It was made clear to Valverde how disappointed the players were with his approach to the game.
The squad like Valverde as a man and a coach, but many senior players believe he's getting it wrong for certain games. Not only the selection upset some, but also Valverde's lack of tactical changes during the 3-0 reverse.
