For Real, this will be a good chance to try to match Barcelona in points, especially since three days before El Clasico, Barcelona will have a difficult match with Bayern in the Champions League, and Real will have one more day of rest, which is important. In addition, this will be the last match for Real and they have a very good winning streak at home, and the matches that Barcelona lost were away. So, considering all the above, I think Real will have a slight advantage over Barcelona in this match.
In terms of player integrity, Barcelona is more advantageous. But in terms of matches, Madrid was lucky to play at the Bernabeu. The injuries of Madrid's best players make me doubt that Madrid can win on October 27. Currently, Barcelona with Flick is able to make Barcelona perform well. Even with limitations and financial difficulties, Barcelona was able to maximize the transfer of players and young players. But I believe anything can happen, I'm a Madrid supporter, I'm definitely happy that Madrid won, but I'm also realistic with the condition of the players.
