Even if they wanted to replace Simeone, can they actually do it? We must remember that Simeone has been for the most part liked by his players, so if those at the top of Atletico Madrid fire him with no justification at all, then the players will get mad about it, they may underperform to get the new coach fired or even ask for their release, so this is not an easy choice to make as I am sure that before any improvement could be seen, a massive drop on the performance of the team will be observed.
Simeone is a good coach and has done a lot for Atletico Madrid because he has always succeeded in taking the club to the champions league even though he hasn't been able to win the champions league for the team even after making it to the final stages twice against Real Madrid but they lost the both finals. Simeone has been coaching Atletico Madrid since 2011 and has won 2 la Liga trophy for Atletico Madrid, the first was in 2013/2014 season and the second was in 2020/2021 season. He's good with the players but for me the team really needs to try the service of another new coach for the club if they can stand the chance to win more la Liga titles and since Diego Simeone has undergone a surgery on his knee requires him to have some rest and time for himself so I don't think Atletico Madrid will experience a decline in performance if they find another coach because the team is very competitive in the la Liga and Simeone has also taken the team to a level that they can still perform better without him.
For some reason, it seems like the opponent always knows very well what to expect from Atlético Madrid. But to me, that’s very easy to understand. Because the coach Simione has been with Atlético Madrid for a very long time. The tactics however did not change that much. Trying the same thing again and again is probably not going to work when you are competing at the biggest level of competition.
Remember, Simione has seen both prime Real Madrid and Barcelona in recent times. The fact that he was able to win La Liga title in that period was actually surprising. But suddenly it becomes not so surprising when you see the level of players that they had. At that time La Liga was really known for being a competitive league. Just like the English Premier League is right now. Now it is not so much like that. And Atlético Madrid is also unable to attract that level of players anymore.
