Since Real Madrid won Girona, they have not been consistent in the league. I agree with you that Girona might play in the European League if they continue with their current inconsistency. If Barcelona overtakes Girona in the La Liga table, Girona will not handle the pressure from Athletico Madrid and Athletic Bilbao to finish in the top four of La Liga.
For now the trophy competition in La Liga is over after Girona lost to Getafe and 90% I am quite sure if Madrid will get the trophy at the end of the season, currently the competition to secure positions 2, 3 and 4 is precisely the most interesting for us to see, Girona's chances of securing their position in the top 4 are even now starting to be threatened by the inclusion of Atletico Bilbao and Atletico Madrid in the competition, Third-placed will be to Barcelona to pull Girona down if they win against Atletico Madrid.
Currently other competitions in the relegation zone also look more exciting because there are several teams that still have the potential to be relegated besides Granada and Almeria at this time, I think the chances of Rayo Vallecano and Celta Vigo are still very large, because in the next few matches they have to face strong teams that have the potential to give them consecutive defeats while Cadiz who are now in 18th position should be able to use their Remaining matches to win victory in order to be able to stay in La Liga next season.
