Bellingham is extraordinary, he can score 5 goals in 4 matches with Real Madrid so far. But Real Madrid still needs a number 9 striker next year. Because his performance is impossible to always score goals, as you said, his real position is only a winger. If Real Madrid bought a great striker, maybe Bellingham's task would be easier, currently Real Madrid is struggling with makeshift players. It will be a challenge if they play in the Champions League.
Real madrid's line up can be like Man city in 2021-2022 without great stickers, but if it's a death lock then Real Madrid will be difficult, Jude is still young, he also needs to be rotated because he can't keep playing and I'm also not sure he can be consistent scoring performance in every match.
Jude Bellingham delivers Real Madrid at tough moments this season, watching play league game sents a direct message to his opponents, he's a potential replacement for Luka Modric and he fits perfectly well in the team. Playing as if he's been with the club for a long time, how would one explain the speedy adaptive style with Real Madrid pattern of game. Jude Bellingham happens to be the best signing that has happened to Los Blancos this summer, he's presence have contributed alot to the team. Carlo Ancelotti will see more useful parts of the new midfielder that's present at a crucial time like this current period.
