Yeah no matter what Simeone's system has worked for Atletico Madrid for many years. I also don't like to watch it though. It has been a really long journey with Simeone so far and it doesn't look like he is leaving anytime soon either. I assume Atletico Madrid board are quite contented with him now as they have extended his contract to 2027.

Maybe they aren't doing well in the La Liga this season. However they are really impressive in the Champions League and quite likely to reach the semi finals soon as well. They can even play a finale there this year as I see them strong enough to eliminate either PSG or Barcelona. I know Barcelona have been superior to them in the La Liga this season but things can change in the Champions League.
Basically in La Liga for them this normal state of affairs, perhaps only with the exception that they do not have to fight for a place in the Champions League, but it is not so often that teams like Girona appear that rise above Atletico.
For Atletico today, victory is more important, so I think that Girona is unlikely to win today, especially since there are losses, Tsigankov will miss the game due to injury, and even in case of defeat, Girona will be 4 points ahead of Atletico in the table, which is very acceptable, but for Atletico a draw is not the best result, because Bilbao can beat them on goal difference, they will play with Villarreal, also a difficult opponent.
Yes, it seems that Atletico Madrid are satisfied with what Diego Simeone has shown, so they will keep him. Even though there are some people who want Atletico Madrid to change their coach because they think Simeone can no longer perform at his best for Atletico Madrid, the management still trusts him enough to stay with them.
In the La Liga match against Girona, it was a very important match for them, because they were also under threat from Atletico Bilbao, yes they were only 2 points ahead and that was very dangerous for their position.
But on the other hand, it won't be easy to beat Girona, because this season they have performed extraordinary with all the situations they have received. They experienced ups and downs in performance which made them unable to maintain their best position in the standings. It was not easy for Atletico Madrid in this match, and it was also not easy for Girona in this match.
