OFK Grbalj goalkeeper Lazar Carevic is a target for Barcelona.
Sport says Bayern Munich are battling with Barcelona and Ajax over the 16 year-old.
Carevic has had trials with Barca and Bayern.
Bayern coach Pep Guardiola has a role that could be more than key. He keeps a good relationship with the player's agent Dami Radoncic, with whom he coincided in 2004 in Qatar, with Al-Ahli.
Guardiola has also been to Montenegro to see him on more than one occasion.
