Age shouldn't be a barrier for the Lamine Yamal to win the award. The young player is extraordinary and plays like a 25 year old with great strength and stamina. He should be given the award if he gets the maximum votes. But with his performance in the finals where he was boxed by Nuno Mendes, his chances reduced drastically.
Even if Lamine Yamal did well in that final match, he is still not the best option for that award. I feel Ousmane Dembele is the most deserving of it. Age is not a barrier to given him Balon d’Or but if he is given that award, then it will only be because of his age and maybe some other factors the big guys knows how they play them without the public knowing.
If the trophies Dembele has won this season was won by Lamine Yamal and didn’t get to win or played in any finals, he will be the most talked player for the Balon d’Or today, but since it’s Dembele in that category, he’s most likely being compared with Lamine Yamal that didn’t win much trophy as much as he did this season. In all ramifications, Dembele is the right candidate for this award following by all the criteria they use to win it, if Lamine Yamal is given then the credibility of the award keeps going into the mud.
