Impossible in today world to see Real Madrid seeling a player like Rodrygo to a broken Barcelona, guys some of you seems to forget that Barcelona is BROKElona, they dont have money at all, they dont have cashflow, the problems are still there, so if Real Madrid ask for a lot of money they cant pay at all.
But don't forget that there is always an alternative as a last option, for example they have to sacrifice something release Raphinha, Frenkie de Jong or other players which if calculated is the same value as bringing in Rodrygo this strategy has been commonly used for many years. Apart from that, Barcelona has a different way of managing the club, where the club is not owned by investors but is owned by many people called "Socios" meaning they can get funding through the public.
As a reminder Barcelona finances have started to improve since last season even they have already completed some pending payments like to Messi well, this is an indication that Barcelona could take another decision although they have to be more careful. The question is, is it possible for Real Madrid to let Rodrygo move to Barcelona? I'm not sure because we know both clubs are competing with each other.
