now the problem is that he already said that he would like to go to barcelona and that it was always his dream to go to barcelona, but i doubt that atlético madrid would facilitate a selling him to barcelona, so we'll see joao felix sitting on the bench at atletico madrid
It's unclear why Diego Simeone doesn't get along with Felix. But it looks like this happened after a defeat in a heated match against Real Madrid in 2022. Simeone was disappointed with the team's performance. In addition, Simeone seemed to feel a physical decline so he put Felix on the bench.
This decision seemed to make Felix dissatisfied, so he was loaned to Chelsea. At Chelsea he looks undeveloped and it seems Simeone is still not satisfied. So Felix's best option should be to leave Atletico Madrid
