The best players did not play aka Robert Lewandowski from Poland and Cristiano Ronaldo from Portugal. I heard jokes that they will not play to make teams even out.. And seems the joke was actually real - the game ended with a draw of 1 - 1.
Here is most important events and minutes for them.
4' Portugal attacking
7` Free kick for Portugal, dangerous but Poland goes of it clean
11` Thiago Cionek get a yellow card
34' goal of Andre Silva
46' the second-half starts
62` - 66` Penatly Kick for Poland and goal by Arkadiusz Milik
Later there were attacks from both sides but no more goals. The game ended as a draw.
The underdogs from Poland made it nice, had some luck due to penalty kick but this is how the game works.
