I think it is between Messi and Mbappe to become the best player in this world cup but Messi is not performing like he is in the youth and Mbappe is still very young to go for it with support of the team mate. Some players score today to still make move in the highest scorer spot. Richarlison of Brazil now in 3 goals scoring on 4-1 victory against South Korea. The numbers to compete will increase when it is in semi finals.
