Those teams got +100m from him when he left, so i'd expect them winning something after his gone. If they did, good for them but Man Utd one PL win in what like 12 years since he left isn't exactly something great.
Man you sound so bitter about Portugal's NT win, does it still hurt? Do you need a shoulder? If i remember correctly, Ronaldo was essential during their run to EURO16. He's the captain, he was their top scorer and didn't he win silver boot after Griezmann? Another thing to remember what's the history of Portugal before Ronaldo. I just went to Wikipedia and their biggest achievement was 1966 3rd place on World Cup. What to say about those times, Eusebio played during that time so it kind of explains something to you as well. After that, they failed to qualify 7 times out of 8 to the World Cup, but right after Ronaldo's arrival they haven't failed to qualify for once. Then same thing for Euro's, and the 4 Euro's Ronaldo has been part of, they have been in the top4 3 times, twice on a final and one victory. On the way, he has scored +100 NT goals for them so i kind of starting to believe he hasn't mattered in their history of football at all.
