In this group the Netherlands will surely advance to the tournament, but Turkey is the favorite to become second after they managed to win against the netherlands
Well, winning the Netherlands right at the opening of the qualifiers will certainly give Turkey a stimulus to keep winning, and there isn't way to say that it was lucky because nobody scores 4 goals against the Netherlands, even playing at home.
But, the Netherlands qualify? I don't know... They were already out of Euro 2016 and the 2018 World Cup... ok, the team is now totally renewed, but they will have to play better.
Yes, Netherlands should play better than their performance in the match against Turkey. Norway and Turkey both are very tough opponents for them in the group. And only the first two teams of a group have a chance to advance. If Netherlands don't improve their game, they could end the group as the 3rd.
