Of course, it's not just you who doubts Girona, but many people besides you are pessimistic about Girona. I personally also doubt that Girona will maintain its performance until the end of the year, but Girona has good motivation and self-confidence to maintain its path. Girona have two difficult games left until the end of the year, namely against Bilbao and also Barcelona in the second week of December.
It is feared that Girona will lose points against Bilbao in the next match, but considering that Girona is playing at home, they have good spirit and confidence to win the match. If Girona can maintain their form until the first half of this season is over, then I am sure they can advance to the Champions League next season.
Girona have really been on good form this season but they’re not a team who would want to challenge Real Madrid, Barcelona or Atletico Madrid for the title, challenging for the title has some requirements it has to meet such as; Squad Depth and Financial Capacity, without squad depth, when the first 11 is out with injuries the team will get all shaky and without finances, there’ll be no room for replacement of injured players.
With 2 top games in hand and considering the injury crisis of Real Madrid and Barcelona I think Girona will end the year on top the log of the table but I don’t expect them to be there a while into the 2nd half of the league, Bilbao are a pretty composed team that could cause worry to any Spanish side left alone Girona, no doubt Girona has been good at home but Bilbao could cause an upset for them over the weekend and they might probably share the spoils.
