I think most agree that UEFA is the hardest and highest quality competition body in football. In club level and national team level. Cr7 has consistently dominated this hardest and the highest quality arena. Here are the indicators: Most goals scored in the UEFA European Championship, including qualifying: 29 goals, for Portugal Leading top scorer in the highest quality football continent's competition. Only player who has scored in 8 consecutive major international tournaments: the 2004, 2008, 2012 and 2016 editions of the European Championship; and the 2006, 2010, 2014and 2018 editions of the World Cup Consistency. No one has been as consistent in 8 2 major NT-tournaments. Not Pele, not Maradona, not Zidane. UEFA European Championship top goalscorer 2012 He scored two goals to the world cup finalist in a do-or-die match. Who could do it? He led his team out of the group of death, scored in the quarter-final. Important moments in major tournaments: Ronaldo would be selected the best young player of World Cup 2006, he lost it due to his behaviour Man of the match against France in World Cup semi-final Man of the match VS Czech Republic in Euro08. Man of the match in the group of death of World Cup 2010. Single handedly destroyed WC 2010 runner-up in Euros, scored twice and elected man of the match vs Netherlands. Again in group of death. Man of the match in the quarter-final of Euro2012 Part of the tournament's team Single handedly saved his team in World Cup 2014 qualifications play off. 4 goals. despite suffering from patellar tendinitis and ongoing doubts over his fitness, being forced to abort practice twice, Ronaldo again assisted the equaliser against the USA in the injury time. Scored winning goal against Ghana. Note that it was group of death. Ronaldo again saved his team from being eliminated from Euro2016. The match ended in 3-3 draw, Ronaldo gave an assist and two goals, single handedly saving his team. In semis of Euro2016 Ronaldo scored and assisted a goal. Again saved his team. Ended the tournament 3 goals and 3 assists all of which came in the most important moments. Played in 3 different semi-finals of Euros, 3 times named to the team of the tournament. Scored a hattrick against Spain in World Cup 2018. Single handedly saved his team. Ronaldo scored the only goal in a 1–0 victory against Morocco Note that, Ronaldo achieved all of these in the top quality football continent, most of the times he was in group of death and yet usually was saviour and man of the match. These are the margins we are talking here, no one is close. Please let me know what you think?
I think you meant to say 'No' because there are players who are rated higher for their NT performances, perhaps even by yourself. Anyway, Héctor Scarone not only scored in 8 consecutive major international tournaments but also in minors. So CR7 is not the only one.
