Jude Bellingham was brought in as one of Real Madrid's future midfielders after Modric and Kross no longer had contract extension options. These two veterans are excellent mentors for young players, but the adaptation process sometimes doesn't work out well for all new players.
There are players who fail to earn the coach's trust when introduced in one or two match, and it's clear that will haunt Bellingham at Real Madrid. But let's be honest that Bellingham is a player who will have a great future at Real Madrid. Meanwhile I agree that Madrid need a quality striker next season instead of relying on existing players, of course that won't help their plans to win lots of titles.
Bellingham is a typical midfielder who is very creative in reading the opponent's condition and I see his style of play suits Real Madrid because he has an instinct when he gives a pass or when he scores a goal. Belligham's strength is also being able to play in several positions, both attacking midfielder and wing midfielder because he has the advantage of carrying the ball in tight spaces. If you look at his playing style at Dortmund he is one of those players who often anticipates possession from opponents and often makes the difference in midfield.
Playing for Real Madrid will certainly be much different from Dortmund, but if you see his abilities it will not be difficult to adapt to the team. I think Real Madrid's weakness is only in strikers now because relying on the young players they have won't make big changes, especially if it's a big game where they are not used to being under pressure.
