Bellingham is only 19 years old. If Real Madrid want him, this young age is a big criterion. It could be a big name like Toni Kroos. He can be indispensable in the midfield. If he has to wait a few years for this, I think he should be patient. I believe he will work wonders together with Vini Jr. Dortmund presents another football player to world football.
Real Madrid have seen the talent and potential that exists in Bellingham so they decided to immediately buy Bellingham, because at a young age they already have the skills to play football which is quite good and when Bellingham has entered Real Madrid, his career will continue to grow because His abilities will always be highlighted in every match.
Real Madrid wants to use their money properly. When they sign a player, they expect long-term service from him. They don't waste money for short-term good performance. Bellingham is a young player. Real Madrid will certainly benefit if they sign Bellingham now. And I believe he will become an essential player for Madrid now as he gradually matures.
