It is true that Girona has performed well this season, but their current existence at the top of the La Liga standings cannot be separated from the inconsistency of Real Madrid and Barcelona, so indirectly Girona has benefited a little because of that.
If you look at Girona's overall performance so far it is quite impressive and they just need to maintain their consistency, in my opinion it is very difficult for a team to maintain its consistency until the end of the season.
And it's not impossible that Girona could make a surprise until the end of this season, I think that would be very interesting if that happened.
They are so focused in winning La Liga, they will bring in support when the time for transfer begins. Just keep your minds open they may fall down or still go higher having Girona at the top a total underdog makes the other clubs to brace up and attack the league.
As we can see Girona took advantage of the momentum well. So Girona steps in La Liga are very well calculated. They know that no club can interfere in Real Madrid and Barcelona eternal rivalry in La Liga so what Girona can do is take advantage of the situation. Girona could lose to both clubs but the probability with the other club is actually higher. So this gives Girona a breath of fresh air sacrificing matches against Barcelona and Madrid but on the other hand they are fighting for big opportunities with the remaining clubs. For me, Girona strategy has been quite effective so far, with the result of 13 matches and one loss being a big achievement.
The issue is not the Real Madrid or Barcelona games for them, they are doing as well as they could without those games, but when it comes down to a situation where you are going to end up with a win over everyone else and win the title if that was possible. The problem for them is the fact that they are going to eventually lose to other teams too, I do not expect Girona to end up staying at the top, beating everyone else, it is not just 2-3 clubs that can beat them, other teams could beat them too, even the lowest ranked team could end up playing a good team on a bad Girona day and beat them.
Girona is lucky to be there, but I am sure that they are not going to end up in the top 2, they are going to go lower, it is just matter of time. I guess that we are not going to end up with a deal where it is going to be a difficult period for them. Hopefully, we are going to end up with a situation that will see the difference between these two situations for them.
