Lamine Yamal not won Champion League and Barcelona's top scorer leading by Raphinha and I think better him if be the winner than Yamal, however depend on vote which the right player win Ballon D'or wish this time not any controversial by voting for players lack contribution for team and leave the player won many tittle exactly Champion League.
I also hope that some players don't get too polite, because for me that player still lacks a lot , I don't like how he does some things on the field, he's not a star yet, he's in a possible promotion but his personality on and off the field is a bit disappointing, in the context of the Ballon d'Or if they are fair, Dembélé should win it.
If winning this award is based on trophy wise then I think Dembele will definitely win the award because the dude has more trophy than Lamine Yamal but if it not rated by trophy wise then Lamine Yamal will win the award because what Lamine Yamal is playing at his age, no player, no legendary or hero has done it at this particular age that yamal is now and so it is an encouraging one and giving him the award will also motivate and boost his zeal and passion in football but the thing is if Dembele doesn't win this award he can never win it again but Lamine Yamal still has time and it is possible he can win in the future.
