Real Madrid invests money but they always invest money in the right places and not spend huge amounts of money in the wrong places like other teams. All the signings Real Madrid have made since then have been successful. Many criticize the signing of new players when Real Madrid sign them but every time Real Madrid have proved them right and the critics wrong.
Jude Bellingham is the best transfer signing this year. Real Madrid is likely to sign Tottenham striker Harry Kane If Harry Kane comes to Real Madrid, Real Madrid will be a strong team in all aspects.
This isn't correct. Real Madrid can also make mistakes and be wrong in their judgment about a player's quality or also about whether or not a player really fits into the team and can contribute a lot to the squad as a whole. You want two examples?
Gareth Bale, the record breaking transfer by Real Madrid who brought him in from Tottenham for more money than they paid for Ronaldo. But I think I don't have to explain to you how it worked out and a comparison between Ronaldo and Bale is also not necessary, but it demonstrates perfectly how decisions made by a club can play out.
Second example is Hazard. This wasn't a bad decision, but nobody can tell whether out of a sudden a player is permanently injured and can't contribute to the squad as expected.
They are making decisions to the best of their knowledge and with high responsibility, but that doesn't guarantee them to be free of mistakes and other fallacies. For now it seems that Bellingham was a great transfer, but give it some time to see whether the expectations will materialize.
