Barcelona expect Neymar to return to training on Wednesday, but are ready to push for a Financial Fair Play investigation if Paris St-Germain pay the 222m euros (£198m) release clause for the Brazil forward.
The 25-year-old continues to be linked with a move to the Ligue 1 club and is due to return from China on Tuesday.
Reports said the player was due in Qatar this week for a PSG medical.
Barca chief Josep Maria Bartomeu said last week that Neymar would be staying.
