Third day in the competition and third success for the Selecçao, who could once again count on their veteran striker Cristiano Ronaldo.
Opportunist on the lookout in the area for an attempt by Rafael Leao, CR7 scored the goal of the break (37e) – sound 906e career goal.
Shortly before, Bernardo Silva had opened the scoring with a marvel of Lusitanian collective action (26e).
After the gap was reduced by the Poles on an achievement by Piotr Zielinski (78e), the Portuguese finally hit the nail on the head with a csc from the unfortunate Jan Bednarek (88e).
A full card which allows Roberto Martinez’s men to consolidate their leadership in Pool 1 of Group A, with three more units on the clock than Croatia, victorious earlier over Scotland (2-1). Poland is six lengths behind.
