According to 'Marca', after Barca's win, there was a heated meeting in the dressing room, where they tried to decipher the problems Barcelona have away from home.
There were no members of the coaching staff at the meeting in Prague, only players. And that's where the dummy was thrown out the pram from a team that is used to winning but not at any cost.
It was the heavyweights in the locker room who took to the floor. "If we play like that we aren't going to win the Champions League.", one of them said at the same time they remembered the shambles against Roma and Liverpool.
And it was precisely that, the memory of playing against big teams that hurt the most. Slavia Prague toyed with Barca, a clearly inferior rival to the big clubs of Europe. Barcelona are aware that, if they had played against a bigger team, the result would have been different.
The criticism didn't just come from inside the dressing room but also outside it. It was seen on the park, in a tense glance from Messi to Valverde that Valverde didn't make back to him.
Also in the mixed zone, where Ter Stegen only spoke on the TV, in which he was very critical of his teammates, at the same time that the rest of them refused to speak to the media after the win in Prague.
The rescheduling of the 'Clásico' has allowed Valverde to give his players some days off. Days where they will calm their nerves before joining up again.
