This has been a poor start for Girona, but there's still plenty of time to make changes so Girona can be much better this season. Some changes are needed within the team, including strengthening the defense, and I think they need to bring in some players in the upcoming transfer window. Competition will be much tougher because several top teams have made major changes, and if Girona can't make the best of it, there's concern this season could be much worse, even facing relegation trouble at the end of the season.
Girona is an average team, and it's not surprising to see them underperforming and not getting good results at the start of the season. So, in terms of utilizing player purchases, I think it also depends heavily on Girona's ability. If their financial resources aren't sufficient to acquire more quality players, then surviving and avoiding relegation at the end of this season is quite good for a team like Girona. Because, as you said, competition this season will be much fiercer, so teams that don't make changes to their lineups will still struggle to compete for a better position.
