This is just a rumor but look at what he has done to make Girona very superior this season. Of course, there will be lots of offers for him from top teams so in my opinion it is very likely that he will leave because for a coach getting an offer from a top team is certainly very difficult to refuse.
However, whether or not the current Girona coach leaves next season, I think it will still be difficult for them to repeat what they have done this season. It is not easy to maintain the consistency of a team if they do not have really strong strength.
Girona performance create good things for the coach with his current contract is going to end 2026 but few clubs which are going to lose their coaches are looking for the suitable replacement, and he is also considered as good because he achieved good results in presence of the Barcelona and Atlético Madrid has never been easy, and he deserved some respect and part of these rumours which are moving around and if he is going to accept any good offer it's going to be no problem because this is not going to happen first time it's all part of the game as well.
But, surely Girona performance in next season is going to be not on same level because we are going watch too many offers about few players and coach as well which are going to hurt them badly and if they are able to bring suitable replacements then surely things will be good for the La Liga as they will be having another competitive team at the top.
