I saw a video recently online, a mimicking video of Bellingham showing how he scores most of his goals in Real Madrid. I just smiled and assume it is just normal hatred from opponent fans. I think it doesn’t matter how he scores the goal, what matters is him getting to score the goal and hovering victory to his team. If he was never in all those positions to kick the ball inside the net no matter how he scores the goal, the accolades won’t be on him now but in the person that scores those goal. He is a midfielder that no one expected to be scoring goals this much and has to be on his debut season. It is just so fascinating and I respect him for that, Real Madrid have really gotten a long term player to enjoy in that midfield.
It is natural that he has haters, especially fans of rival teams, and agrees with you that it doesn't matter how he scores goals because a goal is still a goal and the one who will be considered a hero is the one who scores goals, especially since his presence at Real Madrid is not as a striker but as a midfielder and Real Madrid are lucky because they got a midfielder who turned out to be quite sharp when in the opponent's defense area.
Real Madrid is even more lucky because Bellingham is still very young and he will be able to be even brighter at the club if he continues to improve his game. It is very possible that he will become one of Real Madrid's star players in the next few seasons if he is consistent and doesn't act too much, or include players who are free from injury.
