Bernardo Silva and Cristiano Ronaldo both got on the scoresheet as Portugal ran out 3-0 winners over Luxembourg on Friday night.
Silva gave Portugal the perfect start when he opened the scoring on 16 minutes when he controlled and fired home from close range.
Portugal were in cruise control and Ronaldo made it 2-0 when he ran through on goal and chipped the goalkeeper brilliantly on 65 minutes.
With the three points firmly in the bag, Goncalo Guedes added gloss to the scoreline with a third goal in injury-time, according to MailOnline report.
Elsewhere in Group B, Ukraine continued their fine start to qualification with a 2-0 win over Lithuania to maintain their five-point lead over Portugal.
