Barcelona coach Gerardo Martino led the club's training session on Tuesday after returning to Spain from Argentina.
Brazilian defender Daniel Alves was also present at the Ciutat Esportiva Joan Gamper, but did not take part in the main session as he continues his recovery from an ankle injury.
Sergio Busquets, who returned to full training yesterday following a thigh injury, was one of the senior players who took part in the session.
Barcelona, who host Sevilla in La Liga this weekend, have won each of their three league matches this season.
