Bellingham was Borussia Dortmund's biggest weapon. The same situation was true for Haaland last year. The team got a little worse after Haaland left. After Bellingham left, Dortmund got worse. Dortmund is a team that is adept at recruiting young and talented players. They may be bad this year, but they can make up for that deficiency soon. The observer team is very good.
Jude Bellingham and Erling Haaland are the only players that are making positive impacts on their new positions in their club. Borrusia Dortmund is one of the few elite clubs that have been really consistent in producing young talented players in the past decades. The club keep generating huge figures every transfer window, that's basically what they know best in doing. There's always evidence that they produce brilliant players that have the best peaks in leagues games. Moreover some of these new players struggle and even fail to meet-up the demands for the purpose they got signed in the first place.
True, but it's a bit different for haaland caused by he was a finisher. Bellingham was attacking midfielder which was working even harder in helping its club to win the game. Haaland has proper finishing, and he was only wiating for his teammates to supply him the ball.
The difference between either of players are on how big the efforts are being made by them. Manchester city was not fully relying on haaland. Did you forget KDB, foden or alvarez?
Manchester city had so many talented players while real madrid have some. Ancelotti's decision to end Madrid's transfer journey earlier than other clubs is causing regret among many people.
Madrid could try to sign more quality players to support its club.
