it will really do him more good to go else where to try too since the manager xabi is not looking his way, despite that vicious is a good that we have seen, Mbappe two is a good too but his last season wasn't impressing as much as we expected it to be, I will just say that the manager has to improve in his decision making, Personally i have not seen any improvement in Realmdrid team, we can actually attest to the fact that there performance during the just concluded club world cup was disasterous, I know that the league has not started but will soon start, I think xabi got some work to do, the club got many world star players but the result coming from the US very poor.
Chelsea and Rodrygo would be awesome combination for them, it would help Chelsea a ton and could take that team to a greater level, whereas if we are dealing with Rodrygo staying at Real Madrid, he would not get the playing time he wants and he will be sad. So him going to Chelsea would help him as well and he would be happy.
Sure he will not be in a team as dominant as Real Madrid, so he will need to get used to worse results on games, still not a relegation team though, it's the team that won the CWC which means that he would be going to a decent team. At this point I bet that official discussions are at "is he on sale?" "if you offer the right amount then yeah" levels and nothing official is going on on making this deal happen.
