Of course there was players that moved from a side to another and were called traitors and ugly stuff were trashed on them by their ex fans..
The only possibility to sign him is when Perez open a Real Theater and need a comedian to fall on the pitch and act as dead once touched = That's called hyping, just like using last attacker on earth
Real Madrid won't get any advantage to sign Neymar since Neymar is no longer in a good form. Neymar is also a former Barcelona player, Real Madrid seems not interested to sign an ex-Barcelona player, especially since he is an old player. If it is for improving Real Madrid wingers, they have already many good wingers. So, they don't need any new winger. Another reason is that Neymar often gets injured. Real Madrid won't be happy to have a player who often gets injured.
In the last few years they have always been looking for brilliant young talent so they can increase their performance in the long term.
Neymar's age can still be, but at 31 years old I think Madrid will not be too interested in that and indeed it will be very difficult for Neymar to join Madrid, especially since he has already been part of Madrid's rivals.
Neymar has a high market value he has also enter the age of over 30 years. Real Madrid won't pay for it because it's only a short term investment, Madrid want players who are much younger than that maybe players like Kylian Mbappe, Victor Osimhen
Real Madrid's player transfer activity this season has been quite minimal, much different from their rivals in Laliga, not as usual.
Is it possible that Carlo Ancelotti is preparing for a big transfer?
