Atletico Madrid don't want to take risks by replacing Diego Simeone, so they will continue to keep him until Simeone gets bored of being at Atletico Madrid. Indeed, they are stable under Simeone's coaching, I mean they have not experienced a very significant decline that makes them have to drop out of the top 4 for example.
I can understand why Atletico Madrid are too "scared" to fire Simeone, because there is no guarantee that they will be better under the new coach. but the problem is that they will never know whether they will achieve success if they are in the hands of a new coach or not. Maybe they will be more successful with a new coach.
But this is definitely something difficult for them, because they must also consider everything before deciding whether they will keep Simeone or not. What is clear is that we will still see Atletico Madrid with their coach.
Recently last several years ago Atletico Madrid performance not quit well in Champion League since reached the final round but beaten by Real Madrid, after the higher round achievement Atletico always failure every season their performance and eliminated early at knock out round or quarter final round. Diego Simeone still become Atletico Madrid head coach until right now and the management scare sack him although inconsistency performance not only in Champion League but also Atletico Madrid get downtrend performance in domestic league.
Seems not really has top performance for next season, Atletico Madrid just getting an opportunity qualifying to knock out round or reach quarter final is the highest round. La Liga team has inconsistency performance in Champion League only Real Madrid and next season has the new comer team Girona will get the same result such as Atletico Madrid just qualifying until 16 round only?
He will stay at Atletico Madrid until 2027, which means that in the next 3 seasons, if according to the contract, we will continue to see Diego Simeone as coach of Atletico Madrid. Here you can see how Atletico Madrid continues to trust Diego Simeone to continue with them. Actually, that is their right, but we can't see what they experience if they have a new coach.
And also I feel that Atletico Madrid will find it difficult to fire this coach and even if they want to change coach they will have to wait until 2027. But hopefully next season Diego Simeone can show his best with Atletico Madrid, this is not something impossible for us to see, even though I myself am a little pessimistic.
Maybe they did this because management was very comfortable with Diego Simeone, usually management as long as the coach doesn't make them confused they will be comfortable even if they don't provide anything extraordinary.
