Yes, Girona must at least be able to maintain its current position in order to achieve its target of qualifying for the Champions League next season. Realistically it doesn't seem that difficult to stay in the top four, with the remaining ten games it seems impossible for Giron to drop so many points. But even so, Girona players cannot be satisfied just yet, they must be aware that threats will always come every week. The competitors also always see this opportunity and they will also try to finish in the best position so that we can see that the competition in La Liga will be even more exciting until the end of the season.
No doubt that Girona should secure the position in the top 3 of La Liga standings. Girona only compete with Barcelona to stay in the position of runner-up. Even if they fail to maintain its current position, they can finish in the 3rd place at least. Sure, it won't be hard to stay in UCL zone, Girona is very likely to play in UCL for the next season. Although Girona missed points in 3 matches lately, I'm sure Girona will try to perform again with their best. One of the factor why they missed points in 3 matches, it is because some of key players unavailable in the matches.
Girona seems not having too many competitors if they only target for the UCL zone. I think there will be no change for the team in the top 4 (UCL zone). The possibility of the change is only on the position of the runner-up. This won't affect on the chance of finishing the season in UCL zone.
