French striker Antoine Griezmann trained with his new Barcelona teammates for the first time on Monday following his controversial move from Atletico Madrid last week.
"The first of two sessions scheduled for the day was completed by all available first team players, including the newest incorporations, Frenkie de Jong, Neto, and Antoine Griezmann," the Catalan club reported on its website.
Another French forward, Ousmane Dembele, and German goalkeeper Marc-Andre Ter Stegen were both declared fit after recovering from injuries late last season.
Ter Stegen had been suffering from soreness in his right knee while Dembele had problems with his right hamstring.
There was no sign of Lionel Messi, Luis Suarez, Philippe Coutinho, Arthur and Arturo Vidal who are all still on vacation after taking part in the Copa America.
Griezmann was presented as a Barcelona player on Sunday night, after the Catalans paid the 28-year-old's 120-million-euro ($135 million) release clause.
Atletico described the amount as "insufficient", complaining that Barcelona and Griezmann had negotiated the deal before the buy-out price dropped from 200 million euros at the start of July.
Spanish sports newspaper AS said on Saturday that Atletico will go to Fifa, the governing body of world football, to argue that Barcelona owe them more than the 120 million euros deposited by a lawyer for Griezmann on Friday.
Barcelona travel to Japan on Saturday where they will play friendlies against Chelsea on July 23 and Andres Iniesta's Vissel Kobe four days later.
