Portugal scored a goal in each half to claim their first three points in Group B of the UEFA Under-17 Championship at the Gozo Stadium.
Renato Sanches put Portugal ahead with a shot from 25 metres which goalkeeper Robby McCrorie failed to hold.
Two minutes from time, substitute Luís Mata doubled the score with a long distance shot which caught the goalkeeper out of place after an erratic clearance by McCrorie.
