Atletico Madrid is willing to sell João Felix, who wishes to continue his career at another club due to problems with Diego Simone, which makes it difficult for him to participate. Barcelona had wanted to keep João Felix on a permanent contract, but after seeing Olmo and Nico Williams surpass Felix and Cancelo in international games, the club decided to let them go. The best thing for Felix is to leave the club since staying there will kill his career because he will be unable to play games. Currently, he does not train with the main squad, the next step is that he will be benched throughout the season, I hope they will negotiate with Aston Villa very soon.
Barcelona allowed players to leave because they didn't have enough money to sign all of the new players they wanted. If Barcelona is unable to raise the amounts asked by Leipzig and Athletic Bilbao for Olmo and Nico Williams, the club may sell some of its available players to cover the price of the transfers.
On the contrary, it is better to let Felix go than Atletico Madrid just hanging his status. I mean he was loaned a lot, and when he returned to Atletico Madrid he also didn't get playing minutes. Honestly, I strongly criticize what Diego Simeone did because he was unprofessional and I also criticize the attitude that made Felix have personal problems. I don't know who is wrong, but what is clear is that I prefer to say that both are unprofessional. Felix is one of the players who has good potential, he should be braver to be able to seek other experiences rather than having to stay with Atletico Madrid who don't give him many opportunities. He is still young, the future is still long so he has to take risks.
