The most famous "Barcelona" players Lionel Messi and Neymar joined the team's training sessions.
"La Liga" team leaders, such as returning Dani Alves and Javier Mascherano, had longer holidays as they competed in the World Cup in Brazil.
The tournament ended unsuccessfully for the home team's leader Neymar, who suffered a back injury.
The arriving forward will be examined by "Barcelona" medics, but it is reported that he is completely healthy.
Preparing for the season, Luis Enrique's coached team managed to win 1-0 against "Recreativo Huelva" and play a draw 2-2 against "Nice".
Before the start of the Spanish championship on August 24 against the "Elche" club, "Barcelona" will also face "Napoli", HJK, and "Leon" teams.
