Barcelona players were baffled by coach Luis Enrique's selection choices for Saturday's El Clasico.
Barca shared the points with Real Madrid due to a late equaliser from Sergio Ramos.
Don Balon says Enrique's team selection and substitutions upset senior players for the game.
Many inside the locker room believed Andres Iniesta should've started ahead of Andre Gomes, while it was felt Samuel Umtiti deserved a call ahead of Javier Mascherano, who was lucky to escape a penalty call on Lucas Vazquez in the first-half.
Barca players also believed Gomes should've been taken off for Iniesta, instead of Gomes and leaving Arda Turan on the bench until the final moments was frustrating.
