I am not surprised by Girona's performance. The performance was basically what was expected from Girona. As great as they were at the start of the season, this was completely unexpected. However, Girona have dropped out of the title race after losing three of their last five matches. Even now, second place in the table is difficult for Girona to hold on to.
That is their realistic target, maybe at this time Barcelona only continues to try to win 3 points every La Liga match. Meanwhile, Girona's chances of returning to number one also seem impossible. It seems that they are starting to realize, indeed they have not been able to be at the level of Real Madrid and Barcelona. Other news is about Girona coaches who are in demand by many clubs. Míchel is reportedly in demand by Chelsea, this is because Pochettino did not have a big impact on Chelsea.
It cannot be said for sure how Barcelona will play in the upcoming matches in La Liga. But if the Barcelona team is eliminated from the competition in the Champions League, then in the upcoming matches in the La Liga, we will see more excellent performances from Barcelona. But it will be difficult for Barcelona to continue to perform consistently well in both La Liga and the Champions League.
I haven't seen any news yet that Chelsea are interested in Girona's young Míchel. To be honest I personally don't think Míchel is an experienced coach. He is not experienced enough. However, he has been able to make unprecedented progress in Girona this season. It was a wonderful thing. Perhaps this is why the Chelsea management may be interested in Míchel.
