Girona's performance has indeed declined. it wasn't as consistent and strong as it was at the start of the season. This match was the fifth defeat in the 29 matches that have been played.
I believe this is expected, i once discussed that Girona do not have the squad depth to continue to push for the La Liga title with Real Madrid chasing tightly, and also Barcelona and Atletico Madrid desperate for champions league places. The biggest task now is for Girona to remain in the champions league places, do you think they can achieve that
