For many players joining teams like Real Madrid is more like a dream where there were many superstar players playing for that team also usually whenever Real Madrid wants to hire a players they always have a higher chance than other teams, that's why I think there is a high chance for Jude Bellingham to join Real Madrid if they send him an offer.
reportedly madrid has officially is the team that bellingham chose because as you said, real madrid is the dream team of every world's top football player. it's just a matter of waiting for approval from Dortmund, so next season Bellingham will officially play for Madrid
madrid is after bellingham because they have great hopes that one day they can replace modric, even so i see that a midfielder like modric is very difficult to find again
