Nobody cares about what players do in the group stage, too bad if he was injured but the fact is, 5 CL goals is hardly impressive regardless of the reason. Poland was eliminated at the group stage of the Euro with 0 win. Bayern lost in the quarter finals and Lewa wasn't on the pitch, are you discovering the way the Ballon d'or works?
2018 : Modric, WC final
2016 : Ronaldo, European champion
2014 : Messi WC final
2012 is the exception of the decade with Messi winning after only a CL semi final. You know how many goals Messi scored in 2012? 91 in 69 games, along with 22 assists, something that was never done in the history of football. And even with such a display, some people thought he didn't deserve it because he didn't reach any final or win any title. Lewa scored 48 goals in 20/21 so.... Messi was in a different universe.
