I will obviously support and hope that Portugal wins this match against Turkey and Portugal should win this match because on point table they are a far better team than turkey. And obviously, Ronaldo is going to cause a lot of problems for Turkey's defense. Frankly, I don't think that Turkey's defense will be able to handle Portugal's attack.
There are still four whole months before this match, so now it is quite difficult to say who or which team will be in what form and to make a prediction. I do not think that Portugal is much stronger than Turkey to speak of a clear advantage, at least I hope that the match at home will give an additional advantage and Portugal will win.
I agree in the sense that if the team of Turkey really plays to their best of their ability the distance between them and Portugal is not as large so they could win in a good day.
However the big differencesis they do not have a player like Ronaldo, if Ronaldo wants to go to the world cup and say goodbye to his national team in the best possible way then he needs to be a huge factor during that game and the next one that they will most likely have to play against Italy, otherwise the chances to see Portugal at the world cup will not be as high as we think.
