Sevilla have released a statement condemning fan violence after a Juventus fan was stabbed ahead of their UEFA Champions League game.
The pair are due to meet on Tuesday evening, and violence erupted in Seville on Monday after a confrontation near the city centre.
One fan was stabbed in the incident and taken to hospital, while two others received minor injuries.
The Juventus supporter is 25-years-old, and is currently being monitored at the intensive care unit at Virgen del Rocio hospital. His diagnosis is severe but he is stable.
Sevilla have condemned the attacks, stating that the fans "do not represent the tolerant and respectful values held by the club", claiming that such incidents "tarnish the image of the club".
Reports say that the violence began when a group of Sevilla fans attacked the Juventus supporters on Avenida Reyes Catolicos.
Police were forced to break up the confrontation, and are investigating the violence, but no arrests have been made.
Tuesday's Champions League clash between Sevilla and Juventus takes place at Ramon Sanchez-Pizjuan Stadium, with more than 800 security personnel expected to be in place.
