The 33-year-old still has 18 months left on his current deal with the Catalan giants.
However, Mascherano has struggled with injuries and has fallen down the pecking order under Ernesto Valverde.
"What happens with Mascherano we will see soon," Amor told Movistar.
"We have to see the movements and how everything happens.
"Mascherano is a captain, he is a winner and he is very important for us, when he plays and when he does not play, when he is injured or on the bench."
