The Premier League club have also shown an interest in the centre-back due to injury problems
Liverpool have shown an interest in signing Manchester City and Spain centre-back Eric Garcia, according to reports in England.
Barcelona tried to sign Garcia, who left Camp Nou in 2017, in the summer but could not reach an agreement over a fee with City.
Garcia, 19, is out of contract in the summer, though, and is set to leave for free having told the Premier League side he doesn't want to renew.
Therefore, City could be more willing to do business in January given the prospect of losing the youngster for nothing at the end of the season.
Garcia has expressed a desire to return to Barça, but Liverpool have emerged as a potential competitor for his signature.
The Premier League champions have been left devastated by injuries in defence, with Virgil van Dijk and Joe Gomez both out long-term.
However, whether City would be willing to negotiate with a Premier League rival in January remains a different issue altogether.
Barça are confident that sooner or later -- in June if not January -- they will bring Garcia back to the club where he developed.
