Portugal boss Fernando Santos has admitted that his team could have done more in Friday's 2018 World Cup qualifier against Andorra, which finished 6-0 to the Euro 2016 winners.

Cristiano Ronaldo scored four times for the home side in Aveiro, while Joao Cancelo and Andre Silva were also on the scoresheet against a team that had two players sent off in the second period.

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.
