The Argentinian international looks set to be one of a number of players to leave the Nou Camp in the coming months, as the club set about a big transfer window after seeing a recent FIFA imposed ban suspended.
Mascherano left the Reds to join Barca in 2010 after three seasons at the club under Rafael Benitez, where he developed into a fans’ favourite thanks to his committed playing style.
The Anfield side have been linked with an offer of around £12m to bring him back to Merseyside, and it is understood that the player himself is open to the idea.
Napoli – managed by Benitez – are also thought to be in the fight, but the South American is more attracted to the idea of returning to the Premier League than switching to Serie A.
Liverpool are rumoured to have made a holding midfielder to work alongside and provide cover for captain Steven Gerrard a transfer priority, and can offer the 29-year-old Champions League football on the back of an impressive campaign.
Mascherano has had a rather unproductive spell at Barca, playing second fiddle to Sergio Busquets in midfield while often being used as an emergency centre-back.
