However, Santos was looking for a little bit more from his side after scoring twice inside the first four minutes of the Group B contest.
"We had two goals very quickly and we had everything to speed up the game and take advantage," Santos told reporters. "We fell asleep a little before the end of the first half and didn't do quite what we should've. In the second half, we came back well and scored goals and created many opportunities."
Next up for Portugal is a clash with Faroe Islands on Monday night.
