Marcelino is under consideration at Sevilla.
The former Valencia coach is available after leaving Olympique Marseille a fortnight ago due to fans' pressure.
Sevilla are seeking a new coach after Monday's dismissal of Jose Luis Mendilibar.
Relevo says Marcelino would be 'both attracted and doubtful' about this approach and new contact between the parties is expected in the next few hours.
Marcelino has had a previous spell in charge of Sevilla for the 2011/12 season.
