For now it seems like Joao Felix is staying at Atletico Madrid. He has been rumoured with some teams but his asking price is quite high. In this case it wouldn't be easy for him to be signed on a permanent deal. He still has 4 more years with the team as well. I think the biggest thing that can happen now could be to see him being loaned to another team again.

Until Simeone leaves the team which is likely to happen at the end of his current contract Felix is likely to continue his life like this. But after Atletico Madrid bring a new manager Felix can start to find a place for himself in the team finally maybe.
