I totally disagree with how you downplay the strength of that Chelsea side and don't get why you feel the need to compare it to Barca, Real, Bayern when we're talking about games against PSG & Atletico. In no way is it comparable to Totti's career at Roma, who also had many individually outstanding games against stronger teams even though more often than not the overall quality of his team let him down and Roma lost. You're basically saying Hazard doesn't need to stand out at all, when his team plays badly, to prove he's one of the best players in the world. That makes no sense at all. Hazard needs to show his top level in the CL and for the nationalteam. If his teammates let him down and it's not enough to win games, fair enough, I certainly won't hold it against him. But that's not what happened in the past 2-3 years. And blaming everything on his teammates, who, if I understand you correctly, totally fail to put him into a position to show more, seems very wrong to me. He's not a poacher, who's 100% dependent on service. He's a well rounded attacking midfielder, who has a lot of freedom and sees a lot of the ball. He just needs to do more with it when it matters the most. Being surrounded by quality players and coached by arguably the best manager in the game today can't be that big of a hindrance.
Also, none of what you've written explains his underwhelming performances for Belgium against mostly inferior teams, while De Bruyne doesn't seem to have a problem to excel.
