The appointment of Luis Enrique has changed the situation, says Brovarone.
"Luis Enrique has put everything back up for discussion," he said. "His contract is not lavish, he earns 3.2m a season.
"The two parties [Barca and Mascherano] are talking. Because of what Enrique wants, discussions have reopened. Some things still need to be resolved and when there are figures involved there is always a risk.
"Barcelona are obliged to prolong his contract but the player doesn't seem to agree, so the situation could go on for a while.
"Mascherano's goodbye was certain before Luis Enrique's arrival. Then, discussion reopened on a subject that was already closed.
"Tamer went to Barcelona to find out what is going on and today, he remains there."
