No. Here’s where you’re wrong and how your post was debunked by kc7’s post. You said this:
“The Euros is a much harder tournament to win, and the fact Ronaldo did it with an unfashionable side that haven't been a 'big team' on the international stage is an incredible achievement.”
Let’s leave aside the notion of the Euros being harder to win (very debatable IMO, and would be for anyone who actually watched the Copa America this year and saw the SA teams kicking lumps out of eachother). Also, the Euros has been won by a number of unfancied teams so how hard is it really? It’s certainly not the World Cup, which is exclusively won by strong teams. But as I said, leaving that aside….
You said ‘Ronaldo did it with an unfashionable team (false, Portugal has a tremendous history in club and international football) that haven’t been a big team on the international stage (false, see above) and that it was an incredible achievement (arguably true, given that it wasn’t a vintage Portugal team, whatever their history).
But it’s true in the same sense that Greece winning the Euros was, or Denmark winning the Euros was, i.e. if Ronaldo was not in the team, it would have been construed as a lucky, one-off win.
Ronaldo’s mere presence in the team has enabled people to construct a narrative that it was because of him that they won (and you also insinuate this), a notion which doesn’t stand up to the slightest probing. Had he won the golden ball and the golden boot, had memorable, iconic performances a’la Van Basten, scored in the final etc, you’d have to construe it as an epic carry job to a title. But that is not in fact what happened.
It is not debatable at all. It is nowhere near. Since 2002 (when Brazil won the WC), South American teams have been shit. Between them, they have 0 World Cups, 1 finalist and 3 semi-finalists. Compare to Europeans who have 4 World Cups, 7 finalists, and 13 semi-finalists. Yet somehow we are going to believe that the competitions are of the same level.
Let's see what has happened since then when South American nations faced European ones in World Cups.

Essentially, we can pretend that the competitions are the same strengths (cause those teams kick each other), but since Messi and Ronaldo play with their countries, European teams dominate South American teams, and it is not even close. When it matters most (lose or you are out), in 18 matches, the Europeans have win 14 times (78%) scoring twice as much.
Winning Euros is almost as difficult as winning the World Cup nowadays. Because South American teams are a bit shit and irrelevant. When they face European teams, they go home.
