The Spanish giants are believed to have made several offers for the Brazil international, including one of 100m euros (£92.4m) plus Philippe Coutinho.
However, those bids have been rejected with PSG holding out for more money.
“The player is happy to reduce his wages from 38 million euros net to 23 million euros net,” said Balague.
“It is an interesting situation at Barcelona. They feel they have to try really hard to get him back.
“Lionel Messi, Gerard Pique and Luis Suarez want him back but also the president Josep Maria Bartomeu has two more years in his mandate and he wants to leave a big legacy. Can you imagine all those players that have been mentioned and Neymar as well?”
Neymar is currently training alone at PSG, although that is understood to be part of a scheduled programme rather than related to the transfer saga.
Real Madrid have also put forward a deal that includes money as well as Gareth Bale and James Rodriguez but, like Barcelona’s bid, that has been rejected.
