Girona is only one point ahead of Barcelona and La Liga still has ten games remaining, a change in position is still possible in that time period. Being one point behind Girona is not difficult for Barcelona to move up to second place, I still believe Barcelona is able to shift Girona's position. but it is very difficult for Barcelona to catch up with Real Madrid's points, which is very consistent in maintaining its performance.
Barcelona and Girona will also face each other in week 34, the results of this match will really determine who will be runner up. Girona only needs to maintain their performance if they want to appear in the Champions League next season. Being in the top four is a good achievement for Girona even though they failed to become champions or finished in second place.
Girona's performance has declined slightly at the moment, they only got 2 wins from the last 5 matches and suffered 3 defeats.
With its current performance and only 1 point ahead of Barcelona, of course the possibility that Girona will be replaced by Barcelona in second place is very big, especially now that Barcelona's performance has improved.
Targeting to finish in the top 4 is very realistic for now and that is good enough for them considering that Girona is only a team that was not seeded at the start of the season.
I think if they can only finish in the top 4 and get a ticket to the UCL, it is very possible for them to get it.
