For a team of such talent and technical ability Portugal have rarely ever had really good striker in the modern era. Figo and Ronaldo both were/are reliable goalscorers but from attacking midfield or wider positions but I can only remember Nuno Gomez and Pauleta as traditional central strikers and while they were both OK, neither pulled up any trees.
Portugal have always struggled for goals a bit. They can't line up against a back 5 of Forde, Kelly, Keogh, Duffy and McClean every game!
