And so for Ronaldo, it is now more important than the club to perform well in the jersey of Portugal.
However, Portugal's next match is against Switzerland. Switzerland is not a weak team. However, I believe if Ronaldo performs well, Portugal will be able to fend off Switzerland.
Of course Ronaldo has more priority to appear in the world cup with the Portugal national team because if I'm not mistaken, Ronaldo currently without a club. Even though if he is currently a player at one of clubs still will not change his decision to focus more on Portugal, considering that as you said this is his last chance to appear in the world cup (based on Cristiano Ronaldo's current age)
Ronaldo will now focus more on winning the World Cup. Yesterday, in the match round of 16, the Portugal team got a wonderful 6-1 victory against Switzerland. Although Ronaldo did not score any goals, the performance of the other players on the team was very good. Every player in the team continued to push themselves to the maximum to qualify for the World Cup finals. Ronaldo will now want to perform better in the upcoming matches. The people of Portugal will remember Ronaldo forever if he can perform well on the World Cup stage.
