Sevilla have made a 'take-it, or leave-it' offer to Bayer Leverkusen defender Juan.
The Brazil international has long been the subject of negotiations between Bayer and Roma, but Sevilla have made contact with the defender's agent, Alessandro Lucci, this week and tabled a four-year deal worth £1.4 million-a-season.
Lucci has already informed Bayer chief Rudi Voeller of Sevilla's interest and warned that the Spanish Liga club want an answer in seven days' time.
