I agree with you, exactly as you have explained it, he will be proud of getting the jersey number of a legend which I believe he knows the task ahead of him as someone putting on the jersey number but this will also motivate him to really perform like the legend who he's taking the jersey number or do more better than the legend him self we never can tell.
Bellingham is a good player and his coming to Real Madrid will expose him more for players who are at his his agel doing wonders also.
Jude Bellingham will be the nex zidane if we look at the jersey number he will use next season. With his young age I think he will be able to realize all the challenges that are imposed on him. Real madrid welcomes him as a player who will make a big difference for real madrid next season. Real madrid this season has of course suffered a big setback, be it in the laliga or the Champions league.
So that in this season transfer window, Real Madrid will bring in several players to strengthen themselves for next season. Hopefully Harry Kane can be brought in by Real Madrid in the transfer window this season because if he joins Real Madrid I'm sure he will get a trophy in his football career.
