What Joao Felix has done so far has also made Barcelona happy and Barcelona's decision to respond well to his desire to play at this club has at least paid off, with the very little money they have spent in the transfer market and with what is currently being shown it is quite profitable for Barcelona, and the next thing is how they patented Joao Felix as a full Barcelona player.
Joao brothers aka Felix and Cancelo looks really different when they were playing in their old teams and when they play for Barcelona, I expect Barcelona will sign both of them permanently. Barcelona need to prepare at least 200 Million Euros because Atletico Madrid tend to ask ridiculous amount.
