Felix is really happy and from his performance and his facial expressions you will know that he is happy.
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.
Felix definitely living his dream, that was something he wanted for a very long time. I hope that he does well enough, feel like he could definitely do something that would make a lot of sense for him on the long run. I believe that we could see Barcelona growing a lot higher this way.
I mean the yare not spending the worlds on transfers, and getting players that actually want to play there. They are a big club with a great name and there are a lot of players that loves them, so they just pay the salary, and just a bit of transfer fee every year. They could just make it work in a way where they will end up with much and much less expense, and with their growing income from the success they get, they may repay the debt.
