It's too much indeed when the choice of number 5 bellingham is associated with Zidane in the past, of course there will be a separate burden if the burden must be like Zidane attached to bellingham.
I don't think Bellingham's arrival will replace Modric or Kroos, precisely because the two mainstays of Real Madrid's midfield are old so this team needs regeneration and Bellingham came for that.
but I was a little surprised by bellingham's very high transfer fee even now bellingham is Real Madrid's second most expensive transfer after Hazard, I hope bellingham can do better with the high price (unlike Hazard)
I don't even think so. It seems like that ancelotti will be combining bellingham x modric/kroos. It's caused by if bellingham is not yet having a lot of experience. I think that he can learn even more from playing together with modric or kroos.
He needs a lot of time to develop himself to be a world class midfielder. I think that this will be the reason why real madrid has even tried to extend the contract from kroos and modric. It's caused by these guys will be really helpful to develop bellingham to be even a better player. He has no a lot of experience when playing in the dortmund. He will get what he wants when he will be starting his journey in real madrid.
Since bellingham was a potential midfielder and dortmund priced him so high caused by the club saw his potential. I hope what you said will come true caused by kroos even a bit skeptical with the price to get bellingham from dortmund.
