Petar Durin turned out for Croatia U18s against their Czech Republic counterparts earlier today.
The teenage Pompey keeper played the full 90 minutes of a 1-1 draw in the Slovakia Cup.
Croatia – who are managed by former international star Josip Simunic – took an early lead, but their hosts managed to salvage a draw courtesy of a late penalty.
Durin joined the Blues from Atalanta last summer and was on the bench for January’s Checkatrade Trophy win at Southend.
