Newcastle's U18s are currently competing in a tournament staged in the Bosnian town of Foca and still on course to defend the "Football Friends" title that they won in 2009.
United began their 2010 campaign against FK Sarajevo on Friday night in style, with an emphatic 6-0 victory.
That set up a semi-final meeting on Saturday night with Red Star Belgrade, which the young Magpies won 3-2. The Serbians took a 6th minute lead only to be quickly pegged back by a goal from Paul Dummett.
Efforts from Dan Taylor on 60 and 62 minutes then gave United the lead, with Red Star reducing the arrears ten minutes from full time but having a player dismissed.
The final this evening (Sunday) then pits Newcastle against a team from the Croatian city of Zagreb
