The seven-time Ballon d'Or winner has struggled to adapt to life at PSG since his summer arrival, banking just one goal in 11 Ligue 1 appearances under Mauricio Pochettino.
Messi has registered five goals in five Champions League games for Les Parisiens, but he has failed to hit his usual heights domestically and is already being linked with an exit.
The report adds that Barca boss Xavi and right-back Dani Alves are also eyeing an audacious reunion with the 34-year-old, but Messi's father Jorge Messi is against the idea as he believes Joan Laporta and the club "betrayed" them.
Messi is under contract at the Parc des Princes until 2023 with the option of a further year, but the attacker has been left out of the squad for Saturday's clash with Brest as he continues to recover from COVID-19. body check tags ::
