Ernesto Valverde had all his players back together on Thursday after a strange week due to the Catalan Super Cup.
Barça's players had Sunday and Monday off after the Clasico win over Real Madrid and the majority also had Tuesday off as a small group prepared for the Super Cup game against Girona.
Those that didn't train on Tuesday returned to work on Wednesday morning as the rest headed off to Sabadell, where they lost 1-0 against Girona.
On Thursday, though, everyone was back in training together as preparations began for Rayo Vallecano on Saturday, a game which is followed by Lyon in the Champions League on Wednesday.
B team players Abel Ruiz and Iñaki Peña took part in the session, while Riqui Puig was unable to train due to a bruised ankle.
Valverde's only got two players currently missing through injury: Vermaelen and Rafinha. But on Saturday he will also be without the suspended Clement Lenglet.
