They made surprises, but I think they were only temporary. Staying in the top 10 teams in La Liga is good enough. Girona still have a lot of games and good stability to stay on top. I don't believe they will stay on top at the end of the season.
How Girona turned to a formidable team still surprises me. One unique thing about them is their resilience, not minding of they are playing a big side like Barcelona or Real Madrid. I am very convince they will finish the season around the top to securing one of the European competitions.
This is their second season in La Liga because after relegation and restarting La Liga last season they were also directly in the middle of the table at the end of last season and indeed from the improvement for the first season which was extraordinary this time they have something very good to be proud of again.
But to be in the Europa League next season they must try to maintain their current condition which is in a positive trend not to lose this momentum because sometimes for a club with surprising strength at the beginning of the season sometimes has consistency problems towards the end and that happened to Betis last season so if Girona really want to finish in a good position they must try to maintain consistency as well.
