Yes, it is an advantage for Barcelona to beat Cadiz because Girona failed to get points in this match so Barcelona can share points with Girona in 2nd place and now the distance between the two is 5 points so Girona is increasingly losing the opportunity to overtake Barcelona and Atletico Madrid is also putting pressure on Girona in 3rd position, the competition between Barca, Atletico Madrid and Girona is getting fiercer to knock each other out.
In accordance with my predictions, Girona will have difficulty beating Atletico Madrid. I think other teams have studied and know the weaknesses of Girona's tactics so you can see Girona having difficulty winning in the last few matches. I think that is the minus of the underdog team. When they appear surprising, other teams will try to find their weaknesses. And when their weaknesses are exposed, it will be very difficult for them to change tactics because they don't have enough players to rotate. It's not like big teams can change game tactics and put players who suit different tactics.
I think Barcelona is certain to finish in second place, but for third and fourth positions and maybe also for fifth position there will be changes. Indeed, at this moment of course Atletico will make a good effort to overtake Girona and in this way, it is very likely that Girona will also drop to fourth position. But yes, if Girona continues with this trend or bad results, then at least Bilbao will still have a chance to overtake Girona. If that happens, then in the end Girona will fail to finish in the top four but indeed, for now I personally am still quite confident that Girona will still be able to stay in the top four, at least finishing in fourth place is still very possible for Girona.
