Netherlands, Italy and Belgium became the 3 teams that managed to achieve perfect points in the EURO group stage this time. However, Belgium will meet Portugal, which looks like in this match, they will probably have a hard time getting 3 points. Indeed, in terms of results, Belgium is better than Portugal, but if Ronaldo has a lot of free space, maybe Portugal will beat Belgium.
Italy is lucky enough to meet Austria, of course Italy will predicted as winner by a lot of people. Maybe Welsh predicted was right. Italy will keep a clean sheet in this match. I think, match will ended with 2 - 0 for Italy
Perfect 9 points can not help them to reserve a spot in quarter final. They have to fight and win their matches in Round 16. Italy and Netherlands can win a bit easily but Belgium will have to show their best performance to win against Portugal.
For Belgium, I am worrying about Eden Hazard because Belgium will need him to fight with strong opponents. Only De Bruyne will be bad because other teams will concentrate their best sources to constrain De Bruyne and his connections to Belgium team mates.
Portugal need to see the best Bruno Fernandez too. The player lost his performance in the group stage and it seems the abuse from Solskajer affects his fitness in Euro.
