With his deal to expire at the end of next month, Pastor is fielding interest from major clubs at home and abroad.
Sevilla management are desperate not to lose the 20 year-old, who they see as a future long-term No1. With senior goalkeeper Bono's reputation growing across Europe this season, Sevilla management have hopes of eventually moving the Moroccan on and replacing him with homespun Pastor.
However, they're under pressure to secure the youngster to a new deal as rivals across Europe make their interest known to his camp.
Pastor came right through the youth system at Sevilla and is a former Spain U17 international.
He made his Champions League debut this season against Chelsea - which was his only taste of first team football this term.
