Hansi Flick declined to discuss refereeing after Barcelona were beaten by Girona on Monday night in La Liga, instead criticising his own side's performance.
Barcelona missed a string of chances in the first half but took the lead when Pau Cubarsí headed home. Girona fought back with two goals from Thomas Lemar and Fran Beltrán to complete the turnaround.
Flick was asked about the winner, which followed an apparent foul on Jules Koundé, but he refused to focus on the officials and blamed his players: "I don't want to speak about that. Everyone saw the situation before the second goal, but Girona deserved it. We defended very badly, especially in transition, we were too open, our midfield was not in the right position," he told reporters.
He added that the team have not been comfortable or well positioned recently and that they are "not in a good place" right now. Flick said he will give the players two days off to try to get them back to their best.
The defeat is Barcelona's second in a row; they host Levante at the weekend.
