However, the Catalan club allege that Neymar is in breach of contract now that he has left.
Four minutes later, Rabiot once again combined with Neymar and the Frenchman scored from 18 meters, beating out Alban Lafont for Toulouse, and after that point PSG settled down substantially but never lost control of the match.
Barca appear to still be reeling after the forward's departure, and despite the phenomenal amount of money they received for him, bringing in a replacement has thus far proved hard.
"FC Barcelona have sent a claim to be made against Neymar for breach of contract to the RFEF for it to be passed on to the French Football Federation [FFF] and FIFA", the statement read.
Barcelona is also demanding 8.5 million Euros in damages as well as an additional 10 percent for the delayed payment. It is also requesting that Paris Saint-Germain take responsibility for the payment of the fees if the player can not do so himself.
Barcelona, Neymar and his father and agent, Neymar Sr, are embroiled in a dispute over bonuses included in the five-year contract renewal he signed in 2016. "This legal defence will be carried out following the established procedures with the competent authorities without entering into any verbal arguments with the player".

Chelsea and AC Milan had previously been linked with signing the 24-year-old but neither clubs matched the player's transfer fee.
Belotti has a € 100 million release clause included in his contract with Torino and the clause can only be activated by clubs outside Serie A.
The French side beat Toulouse 6-2 on Sunday.
Neymar's representatives paid the £200m fee at Barca's offices instead, circumventing La Liga completely.
However, Neymar has clearly not forgotten his Barcelona roots.
Neymar got the equaliser and the 222 million-euro man later completed the rout in stunning style after further goals from Adrien Rabiot, an Edinson Cavani penalty, Javier Pastore and Layvin Kurzawa.
