It's true that even though Real Madrid have collected a lot of points so far and have widened the points gap with Barcelona, their meeting will still be a crucial meeting for both teams and they will try their best to show their good performance.
However, I believe that Real Madrid is superior to Barcelona in every aspect, Real Madrid's strength is more stable than Barcelona, so I think Madrid will win the match again against Barcelona in the second meeting this season.
There's something we call standards clubs and they don't relent but anticipate in competitive race which is beyond these mediocre teams. Real Madrid will end first while Barcelona will settle for second position, that's how these teams stay ontop on the La Liga table without any threatening opponents and the one time we would have seen a difference for them was when Girona stood up to challenge but lacks the consistency to reach far. Spanish football is entirely different from other leagues.
Girona is trying to provide something different in the La Liga competition, but as you said they are not so strong and ready that they cannot compete more strongly at the top of the standings. Even though for some time they could be at the top of the standings, but that didn't last long because in the end Real Madrid was able to take over that position and now they have quite a distance.
The match between Real Madrid and Barcelona will always be an interesting match, because we know what the rivalry is like between them. Even though this season Barcelona is experiencing several problems, in my opinion it will not make the match uninteresting, it will still be a very interesting match.
The season is very clear to know who will win this la Liga league title among the three teams that has come up with excellent performance so far in this season, but the gap Real Madrid is using to top the two teams Barcelona and Girona show that Real Madrid will take first position, Barcelona will take second and Girona will take third position in the la Liga league. Barcelona will never give Girona chance to take the second position back from them, because their manager has solved some challenges that is making Barcelona not to be constants in winning. Even in the champion league competition, many people are still looking up to Manchester city and Real Madrid, but I don't think Real Madrid will win the champions league title this season because Manchester city are in good form to stop Real Madrid and other teams not to embrace the title.
Of course Barcelona will not let Girona shift their position in the standings again, they want to finish in the best place even if they don't become champions.
What concerns me is whether management will not try to persuade Xavi to stay with them next season. After all, what he has shown this season is also not bad, it is proven that he is still in second place and also in the Champions League they are still competing in the quarter-finals of the Champions League. Are they not considering this, because I think there is a process that Xavi has shown and that process is a good process.
