Highlights - Portugal 7-0 North Korea
Portugal coach Carlos Queiroz says his side's 7-0 win over North Korea in World Cup Group G will spur them on for their final group game against Brazil.
After an uninspiring 0-0 draw with Ivory Coast in their opening game, Portugal improved dramatically to thrash the spirited North Koreans.
"Scoring goals always improves confidence," said Queiroz, whose side face Brazil on Friday.
"Playing like we did today, it is a great motivation for the next match."
Portugal have four points after two games but their healthy goal haul means they have almost certainly made it through to the last 16.
If Ivory Coast beat North Korea in their final group game they would finish on four points but, even if Portugal lose to Brazil, there would need to be a nine-goal swing to see the African side go through.
Portugal led 1-0 against North Korea at half time but a ruthless attacking display in the second half proved too much for their opponents.
"I would like to express my great satisfaction to my players for the wonderful way they played, their great attitude, their reverence to the game," said Queiroz.
"It was beautiful football, a great day for Portugal and Portuguese football.
"The players are really happy with the way they played, their attitude for the game, the beautiful football, the beautiful goals."
Real Madrid forward Cristiano Ronaldo scored his first goal for Portugal in two years when he stroked home the sixth of the game.
"To score seven goals in a World Cup is not easy" said Portugal captain Ronaldo. "My team-mates played very well."
