Joao Felix last performance didn't invite deals from other clubs, Barcelona was his best choice which he voice out and Barcelona reached out to him to seal an agreement, I don't see anything wrong with such move. I think Chelsea rubbish his effort and glad he return after the loan expire, because look at Chelsea till today, they haven't recovered from their loss syndrome, only Lord knows where they will finish the season.
As I last read from tweets of some strong sources, I think he had lot of offers on the table including some from Saudi Arabia as well but he chose Barcelona over all as Barcelona was his top priority. Anyway, I get it that to play for Barcelona is his dream but will he really be happy at Barcelona? I don't think so because Barcelona has lot of players right now and I don't think he will be getting regular chances often. I honestly hope that he does have some playing chances because he is a good winger but situation doesn't seems right at Barcelona. Kinda similar to Chelsea...
