Asked by TUDN whether Ronaldo and Co. can win their first world title, the ex-defender said: "Yes, that's how I see it. They have a very good national team. Their players play for big clubs and win a lot of titles. They are very competitive and have a good coach... As things stand today, I think they are a very dangerous team."
Portugal won the Nations League final in Germany at the beginning of June. Martinez's team defeated the Germans 2-1 in the semi-finals and beat Spain 5-3 on penalties in the final.
They continue to rely on 40-year-old Ronaldo, and Puyol waxed lyrical about his old Clasico rival, adding: "He takes extremely good care of himself. He lives for football. His statistics as a centre forward speak for themselves."
