Girona have been in great form since the start of the season. In every match we got good performances from Girona players and Girona players are capable of scoring a lot of goals. They also had a great performance against Barcelona. Girona have only lost against Real Madrid this season. However despite Girona playing very well, the team's chances of winning the title are slim. Because there is still a long journey ahead. It is very difficult for an inexperienced team like Girona to continue their good performance for another 20 matches. That's why I consider Real Madrid, Atletico Madrid and Barcelona as favorites for the title.
It doesn't look like Girona are lacking experience right now, they are playing great and their success I think will depend a little on other factors, such as whether they can keep all the players until the end of the season and whether Michel will remain in the team, or perhaps he is already preparing to become a coach of another teams (there are rumors about Barcelona). It will always be difficult to compete with Real, and if Girona now has such a chance, then they should try to take advantage of it.
I somewhat agree with you. It doesn't look like the Girona team is inexperienced. We are seeing good performances from them in every match. Especially against teams like Barcelona, the boys of Girona have played well. But winning the La Liga title is very difficult. Good performance has to be maintained from the beginning to the end of the season. And in the past years we have not seen any team other than Barcelona, Real Madrid and Atlético Madrid have been able to maintain the consistency of performance for such a long time. If Girona can play consistently well until the end of this season, it will certainly be a huge achievement for them. But personally I think it is very unlikely.
