Anyone who expects Messi to return to Barcelona, I'm sure he doesn't understand about football, it's likely that he is only a child who idolizes Messi

as you said what was expected from Messi when Barcelona already had many talented young players this means they don't need old players anymore. Messi might come back but not as a player but in another position, for example as a coach in the future or even the club owner, who knows right? we don't know how long he is active as a player remembering his old age.
Imagining the good old days is fun, isn't it? Maybe that's what Messi fans imagine, always thinking about how Messi can repeat his best achievements at his old club, but they forget that sometimes everything good has an end and Messi's journey with Barcelona ended when he moved to PSG and now he is enjoying his career at Inter Miami. It won't be like when he was at Barcelona but Messi realizes that everything comes to an end.
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.
