Barcelona are reportedly keen for Neymar to publicly state that he wants to return to Camp Nou this summer.
The Brazil international was left out of Paris Saint-Germain's Ligue 1 opener against Nimes last weekend amid suggestions that he will be moving on before the end of the month.
Barca have been strongly linked with a move for their former attacker, while Real Madrid are also said to be interested in a deal for the South American before the Spanish transfer window slams shut.
According to the Daily Mail, the reigning Spanish champions want Neymar to 'make a public declaration' confirming that he wants to return to the club.
Earlier this week, PSG boss Thomas Tuchel admitted that he was unsure whether the 27-year-old would still be with the French giants by the time that the window closes.
The former Santos youngster is said to be valued in the region of €200m (£188m) by PSG, although both Barca and Madrid are said to have offered various players as part of their attempts to sign the attacker.
