Both Brazilian players are truly talented. I remember Endrick scoring a magnificent goal from outside the penalty area last year; he can't do that every month. If given enough opportunity, he could be a finishing striker for Real Madrid. He might have the potential to be as effective as the phenomenal Ronaldo. They might loan him out to another team for a year to show his potential, but he has the potential to become a key player for Real Madrid starting next year. As for Rodrygo, we all know how important he is to Real Madrid. If they want to let him go, they need a good alternative. In my opinion, he should stay with the team and continue to compete for another year.
I am 99% sure he can't be as good as old Ronaldo, he is good there is no doubt about that but at the moment we need to see what the reality is which is the fact that he is just a talented kid but that's it. Phenom was something different and it would be near impossible for anyone to stop him. He was both strong, fast, agile, and very talented all at the same time. Only downside was that he was mostly injured, and because of that he didn't became the greatest ever.
And Endrick will not be as good as CR7 neither, to be fair I do not need to explain why. But if one day Real decides to part ways with Vini, then Mbappe could move to left ,and Endrick can be their striker, he is good enough to give that chance at this level.
