Chelsea are showing interest in 18-year-old Partizan Belgrade winger Andrija Zivkovic, agent Pedja Djordjevic has confirmed.
Yet another youngster prematurely dubbed as "the next Messi", Zivkovic started his career as playmaker but was deployed on the right wing by former Partizan head coach Vuk Rasovic.
He is also a target for Valencia and Sampdoria.
"We want to review all the options and decide calmly," Djordjevic told Super Deporte.
"Valencia and Chelsea are two of the clubs interested in Zivkovic."
