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.
There are 7 matches remaining for the teams ranked in the top 4 of the standings. With the remaining matches available, it is still possible that we will choose a different position at the end of the season. Barcelona is 5 points ahead of Girona, Girona is 4 points ahead of Atletico Madrid, that is the distance at which they will be able to catch each other. However, in my opinion, for the top 4 positions, we will look at the 4 existing teams that will be there, regardless of position changes and other things.
Girona really struggled when facing Atletoico Madrid in this week's match, even though they were able to take the lead earlier, Atletico Madrid were able to turn the situation around comfortably to 3-1 at the end of the match. It's clearly not easy when they face a team that is almost as strong and they have to play as a visiting team, because the advantage is all on the home side. But regardless of what Girona has shown recently, they must maintain their position at least in the top 4.
