The forward was the subject of a major pursuit from his former club during the off-season, but they are unsure as to whether they will chase him again
"Neymar was a sports area request and the club did everything in order to get him, albeit in a financially sustainable way," Grau stated.
"We made many proposals to PSG. They always rejected them. I don't know if we are going to target him again next summer. Planning for next season will be done in the future.
"We would have been delighted to have the chance to bring Neymar back, but the terms always had to be reasonable.
"If some parameters had been accomplished, it would have been possible, but PSG were not happy about losing him."
