Regarding tactics, Carlo Ancelotti probably won't change his tactics much, perhaps he will still give Joselu and Rodrygo a place in front and Bellingham behind them. But it is possible that Ancelotti will make other experiments to make his tactics difficult for the Girona coach to learn. It will be interesting to look forward to this match.
If we look at the statistics up to now Girona are unbeaten in the last five matches and they seem to be meeting an opponent who is really right for them, I think Madrid will probably break their winning streak if Madrid manage to beat them at home, Ancelotti certainly doesn't want to share points with Girona and for sure he will ensure Madrid get three points from tomorrow's match using another strategy to provide a surprise.
On the one hand, Girona plays as host, maybe they will play with the ability they have to get points and add another series of wins even though they will find it difficult to face Madrid, if it is predicted that the betting market favors Madrid and I predict Madrid will win narrowly 1 - 2 against Girona tomorrow.
