Mascherano is also wanted by Inter Milan, but does have hope of reviving last summer's failed switch to the Nou Camp.
Horacio Zandonadi told COM Radio: "The player would love to hear from Barca.
"His price is around half of what Arsenal wanted for Cesc Fabregas. He hasn't renewed his contract because Liverpool said they would help him find a new club. We're talking about a situation that is much easier than last year, where it was a soap opera.
"Mascherano and Lionel Messi are friends, they get along very well because they have a similar profile in terms of personality."
