Girona squad composition is not perfect like Madrid, so currently Girona is better off letting the Copa Del Rey go rather than losing the opportunity to get the La Liga Trophy, if Girona forces to target all competitions then I'm sure their squad will fail to win the trophy Considering the composition of the players they have, the quality of the reserve players that Girona has is not as good as their core players and if they force the main players to compete in all competitions it will only make the players vulnerable to injury, so it is better for Girona to focus on La Liga as a their target main thing is because winning La Liga has more prestige than the Copa Del Rey for Spanish League clubs.
I believe Girona should have put more effort into Copa del Rey as well. I feel like it's easier for them to win the Copa del Rey than to win the league. Currently, Girona are top of the league with just 1 point ahead of Real Madrid and Madrid has a game in hand. Looking at Real Madrid, it's difficult to believe they won't overtake Girona in the title race.
I'm not underrating Girona, but this is Real Madrid we're talking about, we all know the kind of fighting spirit this team has, they don't give up. I know Girona will put everything they've got for this but it just might not be enough.
In the Copa del Rey, if Girona had won Mallorca, they would have been one game away from the final. That's an easier route to a trophy this season than the league.
I hope they will be able to hold on to the top position in the league till the end of the season though, but I doubt they will be able to.
