Reports have revealed that 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.
The reports also 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.
His comments came after reports that PSG had triggered the release clause, which would be a world record fee for a player.
Should that sum be offered, the 24-time Spanish champions will ask Uefa to consider whether the French club would be in breach of FFP regulations.
The rules, first implemented during the 2011-12 season, stipulate that European clubs cannot spend more than they earned.
PSG, supported by a Qatar fund, were punished in 2014 for breach of FFP. Their £167m commercial contract with the Qatar Tourism Authority was deemed to have an unfair value by Uefa’s independent investigation panel.
They were given a £20m fine, their spending was capped to £49m and they competed in the 2014-15 Champions League with just 21 players instead of the usual 25.
FFP regulations – updated in June 2015 – state that owners can inject cash into a club as long as they can demonstrate how they will reach break-even. And a club will also have to ensure that their losses do not exceed 30m euros (£26.81m) over three seasons.
