It's true that we know that currently Chelsea doesn't have a creative midfielder like KDB or Odegaard who can always supply the ball to his teammates to score goals, but on the other hand, their attack line doesn't have anyone who can do that finishing. If you ask me where Mudryk is placed, I will put him on the bench until the season ends then sell him to another club. Everyone knows this player is very useless and Chelsea has certainly lost a lot because of this worst purchase. I saw that he had failed as a young player and was now nothing more than an amateur football player. It's a shame that Chelsea spent a lot of money on Mudryk last winter.
wait what? Are you confused? 
KDB is at Manchester City and Odegaard is at Arsenal. What does that have to do with Chelsea?
For the striker position I prefer to convince Jackson because in my opinion he still has quite good potential only for now he still cannot show his best performance for Chelsea. On the other hand, currently there is still Nkunku, it's just that we know that he currently cannot be expected with his condition still in the treatment room. As for Mudryk, this is indeed very difficult to talk about because trying to say that he still needs a chance to adapt is also difficult if you look at his current performance and indeed Mudryk is one of the players with a purchase that can be said to be a failure.
Niklas Jackson does have potential, but with big responsibilities at a young age, his mentality is still not ready, especially since he has to defend a team that was very chaotic last season. Nkunku has been out due to injury for 4 months and starting from the start of Chelsea's EPL match, he will recover in about 3 months. As for Mudryk, maybe you already know and I don't need to add more, this player can no longer be expected to play football and it's lucky that Arsenal didn't buy him.
It doesn't matter where KDB or Odegaard plays. First of all I wouldn't put these two players into the same category as KDB is unmatched when we talk about assists as KDB is in the club of 100+ assists historically. Maybe Odegaard can one day reach his number of assists, but that's a very long way to go for him.
It's easy to say what a club needs when you take the best players in the world as an example. Chelsea needs an Mbappe and a 25 years of age Messi. They also need a Zidane. I guess you get my point.
@rendravolt I do understand what you mean though. But I think before trying to find the next KDB, Chelsea should try to build a cohesive team that is willing to work and suffer together. They are buying all these superstars and everyone wants to be the most expensive transfer and earn the most money, but it looks like they don't really take on the challenge and have the back of each other during their games. It is like Chelsea is rolling the dice with high stakes every time the transfer market opens and hope it works out. That's not how a top team is built.
