There is a 7 point gap between Girona and Athletico Madrid, and they would still be fourth if they drop there, there is a 9 point difference between Athletic Club as well, so it wouldn't be really all that simple. We are talking about just 8 games left, expecting Girona to lose 9 more points than Athletic Club in the last 8 weeks would be a little weird
Girona coach will not allow it to happen in their remaining matches, because they have loss a lot in some few matches that made their position to dropped down to third position, and their coach has discovered the causes of their mistakes which they will never allow such mistakes to happen again. Athletic club has performed well in this season to defeated many teams to get to this fourth position, and if Girona repeat their mistakes that brought their points down in their remaining matches, they will take the position from Girona. Real Madrid is still toping the la Liga league table which many people know that they are in a good position to win the title and Barcelona will struggle for second position because Girona is still close to Barcelona to make mistakes so that they can take the second position back from them to make their fans celebrate them.
That should don't be the case because the difference in points is quite large, if Atletico Madrid can actually match or surpass it in the remaining matches, then that means Girona will suffer several defeats during the remaining matches.
It just that I don't believe that Girona will experience several mistakes that will cause them to lose in the future because there is only one complicated match, namely against Barcelona.
For the next match against Atletico Madrid, I think Girona will still be able to show satisfactory results even though it is an away match, at least sharing the points by achieving draw is pretty good solution rather than losing.
In fact, I still have feeling of optimism if Girona is able to surpass Barcelona, which is currently only 2 points apart, Barcelona has derby match against Real Madrid and this is chance of defeat for Barcelona.
If in the derby Barcelona loses to Real Madrid and the Barcelona vs Girona match ends in draw because they performed optimally in the home match then Girona has the opportunity to become runner-up.
